Selected AbstractsPreface: phys. stat. sol. (a) 205/8PHYSICA STATUS SOLIDI (A) APPLICATIONS AND MATERIALS SCIENCE, Issue 8 2008Guest Editor Elvira Fortunato Advances in Transparent Electronics: From Materials to Devices II This issue of physica status solidi contains selected papers presented in Symposium I "Advances in Transparent Electronics: From Materials to Devices II" at the European Materials Research Society Spring Meeting held in Strasbourg, France, from 28 May to 1 June 2007. This was the second meeting in Europe covering this topic. It was attended by scientists from 33 different countries, with special emphasis to the Republic of South Korea and Japan (20% and 10%, respectively, of the total of papers presented). The symposium programme consisted of 9 invited talks, 45 oral presentations and 122 poster presentations, in total 176 contributions, from which 60 were selected for publication in the proceedings, representing nearly 35% of the submitted communications. Topics ranging from the fundamental understanding of physical phenomena to materials and devices have been covered, with special emphasis on the following ones: ,,Materials and processing for transparent electronics ,,Characterization and modelling ,,New devices (nano, micro and macro) ,,New applications The success of this symposium was the result of the contributions of many dedicated people. It is a pleasure for me to thank the symposium organizers (H. Hosono, Japan, J. Wager, USA, G. Kiriakidis, Greece, and S. Y. Lee, Korea) for their availability and help during the preparation and follow up of this symposium as well as all the individual referees, who donated their time to help making this a successful and scientific strong contribution for the international community on transparent electronics. I also would like to thank the two voluntary symposium assistants (P. Barquinha and G. Gonçalo) who helped before, during and after the symposium. Since the work is not limited to what was done before and during the conference, I also have to emphasize a detailed, delicate and long work that has been done after the conference was over, in close cooperation with Prof. Martin Stutzmann and Dr. Stefan Hildebrandt, for the edition of this special issue. I also would like to thank the E-MRS staff (C. Kocher and S. Schoeffter) for the unlimited time, energy and professionalism given for the success of this symposium. Without their assistance the symposium would not have been the success that it was. I also gratefully acknowledge the financial support of our main sponsors who made the symposium possible: ,,FCT-UNL, Portugal ,,Hewlett-Packard, Ireland ,,Horiba Jobin Yvon, France ,,Canon, Japan [source] Optimization of AlGaN/GaN HEMTs for high frequency operationPHYSICA STATUS SOLIDI (A) APPLICATIONS AND MATERIALS SCIENCE, Issue 7 2006T.

[source] 6th International Workshop on Expert Evaluation & Control of Compound Semiconductor Materials & TechnologiesPHYSICA STATUS SOLIDI (A) APPLICATIONS AND MATERIALS SCIENCE, Issue 1 2003Bálint P The EXMATEC workshops are a series of biannial conferences with the aim to bring together research and development specialists involved in compound semiconductor material physics, chemistry, process technology, characterization and device fabrication. EXMATEC 2002 is the continuation of successful meetings, previously held in Lyon, Parma, Freiburg, Cardiff and Heraklion. The central topics were development, improvement and application of new and advanced methods in the fabrication and evaluation of compound semiconductor materials and structures to develop understanding of the interrelationship between structural, electrical and other material properties and device characteristics, such as performance, reliability, reproducibility, lifetime, yield, etc. The conference topics apply to all compound semiconductor materials (III,V, II,VI, IV,IV, II,IV,V2), related structures and processing steps (from substrate and epitaxial growth to complete devices) and cover instrumentation and characterization issues. The full Proceedings of EXMATEC 2002 are published in the second issue of the new journal series physica status solidi , conferences Vol. 0, No. 2 (2003). As one representative example of the topics presented at this conference, the cover picture of the present issue issue of phys. stat. sol.

(b) 245/3PHYSICA STATUS SOLIDI (B) BASIC SOLID STATE PHYSICS, Issue 3 2008Christopher W. Smith This is the third Special Issue of physica status solidi (b) focusing on materials with a negative Poisson's ratio or other ,anomalous' physical properties. This issue contains selected papers from the First International Conference on Auxetics and Anomalous Systems held at the University of Exeter, UK, on 4,6 September 2006. Around 50 participants from all over the world as well as from a wide range of scientific and engineering disciplines contributed to what was a highly successful conference. This conference follows in the footsteps of two previous workshops held at the Mathematical Research and Conference Centre in B,dlewo near Pozna,, Poland, in 2004 and 2005 [1, 2]. The papers selected for this issue publish recent results obtained for ,anomalous systems' in experiment, theory and computer simulations. In the following we summarize very briefly their contents. Alderson and Coenen compare the performance of auxetic composites to similar systems with conventional positive Poisson's ratios. They find that there are indeed differences which appear to arise from the change of the overall Poisson's ratio of the composite, some beneficial like a rise in impact tolerance at low impact rates, and others deleterious such as the reduced tolerance at higher impact rates. This is one of the first investigations of possible applications for auxetic materials. The two papers by Gaspar and Koenders both examine the effects of disorder upon anomalous properties, especially negative Poisson's ratio. In the first one Gaspar demonstrates how a mean strain estimate fails to predict negative values of Poisson's ratio because of an inability to account for local fluctuations in elastic properties. For instance it is shown that the volume fraction of auxetic regions in an globally auxetic material (measured experimentally) are smaller than a mean strain homogenisation would require. Koenders and Gaspar explore the elastic properties, and especially Poisson's ratio, of a heterogeneous 2D network of bending beams. They predict auxetic behaviour arising from localised disorder in the packing, and therefore effective locally aggregated elastic properties of the beams. In the three articles by Gatt et al. and Grima et al. models based on simple geometry are used to explain the behaviour of seemingly disparate systems, i.e. 2D honeycombs systems and zeolite SiO2 networks. Two papers concerning honeycombs demonstrate relationships between elastic properties and structure and the bounds for auxetic behaviour. The paper concerning the zeolite Natrolite uses numerical force field based energy minimisation methods to simulate the response of this particular zeolite to applied forces and then simplifies the predicted properties even further by considering structural units as rigid 2D polyhedra linked by flexible hinges. In a similar vein, though using a different approach and concerning a very different form of matter, Heyes shows how the heterogeneity in an assembly of particles in a liquid can affect the elastic properties of a liquid and notably the infinite frequency Poisson's ratio. Heyes uses the Molecular Dynamics approach to simulate a Lennard,Jones fluid under various pressures, notably comparing behaviour under positive and negative pressures. In their first paper Jasiukiewicz and co-authors derive elastic constants of 2D crystals for all four classes of 2D crystalline solids: hexagonal (isotropic), quadratic, rectangular, and oblique systems. In their second paper they demonstrate conditions required for auxetic behaviour of 2D crystals. Auxetic solids are further divided into those with some negative Poisson's ratios (auxetic), all negative Poisson's ratios (completely auxetic) and no negative Poisson's ratios (non-auxetic). Lakes and Wojciechowski consider counterintuitive properties of matter, like negative compressibility, negative Poisson's ratio, negative thermal expansion, negative specific heat, and negative pressure. They present and interpret experimental observations of negative bulk modulus in pre-strained foams. They propose also a constrained microscopic model which exhibits negative compressibility. Finally, they solve a very simple thermodynamic model with negative thermal expansion. Martin et al. take a long stride toward a real world application of auxetic materials with a wide ranging study starting with numerical modelling of a wingbox section to experimental testing in a wind tunnel. They show that an auxetic core in a wing box section can allow a passive aero-elastic response which can be tailored by careful design of the core so that camber, and thus drag, is reduced with increasing airspeed but without sacrificing structural integrity. Miller et al. consider another anomalous physical property, negative thermal expansivity, and its application in the form of particulate composites for amelioration of stresses arising from thermal mismatch. They show via experiments that particles with a negative coefficient of thermal expansion may be used as a composite reinforcer to reduce overall thermal expansion and behave according to the standard volume fraction based models. Narojczyk and Wojciechowski examine the effects of disorder upon the bulk elastic properties of 3D fcc soft sphere systems in terms of particle size. Systems, such as colloids, can be thought of in such terms. The study shows that higher order moments of probability distribution do not influence the bulk elastic properties much, but that lower moments such as the standard deviation of particle size influence the elastic properties greatly. The "hardness" of the particle interaction potential is also important in this context. In general, it is shown that the effect of increasing polydispersity is to increase the Poisson's ratio, except the [110] [10] directions. Scarpa and Malischewsky in their paper on Rayleigh waves in auxetic materials show how the Rayleigh wave speed is affected by the Poisson's ratio. The behaviour is complex and depends upon the homogeneity within the material, for instance slowing with decreasing Poisson's ratio in isotropic solids, but showing the reverse trend and increased sensitivity to Poisson's ratio in laminate composites. Scarpa et al. explore the buckling behaviour of auxetic tubes via three types of model, a simple beam mechanics and Eulerian buckling model, a 3D linear elastic FE model and a bespoke non-linear continuum model. The more sophisticated models provide increasing insight into the buckling behaviour though the simple beam model predicts reasonably well in the pre-buckling linear region. Some unexpected and interesting behaviour is predicted by the continuum model as the Poisson's ratio approaches the isotropic limit of ,1, including increasing sensitivity to Poisson's ratio and rapid mode jumping between integer wave numbers. The paper by Shilko et al. presents an analysis of a particular kind of friction joint, a double lap joint, and explores the effects of altering the elastic properties of one component, in particular it's Poisson's ratio. The manuscript introduces the evolution of smart materials from monolithic materials, and the classification of composites exhibiting negative Poisson's ratios. The paper then presents the case of a double lap joint and performs a sensitivity type study, via a 2D FE model, of the effects of changing the elastic properties and degree of anisotropy of one section of the model on various parameters defining the limits of functionality of the joint. The main finding is that an enhanced shear modulus, via a negative Poisson's ratio, can endow such a friction joint with superior performance. Manufacturing of auxetic materials on a commercial scale has proved to be the largest obstacle to their fuller exploitation. The paper by Simkins et al. explores one route for post processing of auxetic polymers fibres produced by a conventional melt extrusion route. Simkins et al. showed that a post process thermal annealing treatment, with carefully optimised parameters, was able to even out otherwise inhomogenous auxetic properties, and moreover improve other elastic and fracture properties often sacrificed for auxetic behaviour.

Dederichs The ,k network aims at encompassing the whole community of European groups working in the area of ab - initio materials modelling, including very many small groups and isolated researchers. Historically, the activities started in the 1980s in Trieste with the workshop series entitled "Total Energies and Forces". Since then, it has operated on the European level in various forms, with funding from various EC/EU and ESF sources, beginning more than 10 years ago with the EC's Human Capital and Mobility Programme. In that time, ,k has done much to make Europe the leading area in the world for research in atomic-scale ab - initio computer simulation of all types of materials, their structures, properties, and processes. To a large extent, this has been done by nurturing scientific excellence and collaboration in what might be called "the ,k family". The ,k Network is presently organized around 15 topical working groups. Over the years, the ,k network organized three large scale conferences in Schwäbisch Gmünd, Germany (1996, 2000, 2005), attended by hundreds of scientists from all over the world. The next ,k Conference is to be organized in Berlin in 2010. These ,k Conferences are unique events fully dedicated to the ab - initio research. In addition, the network organizes a variety of meetings and topical workshops every year. The core activities of the ,k network involve editing every two months a ,k newsletter with typically more than 100 pages, which contains a "Scientific Highlight", announcements of conferences, workshops and vacant positions, news of various ESF and EU funded networks, including reports on workshops, and abstracts of submitted papers. The ,k has its own web pages (http://psi-k.dl.ac.uk) which inform about the Network, its structure, and how to get involved in ,k activities. These web pages are also the repository of the ,k newsletters and Scientific Highlights and details about the ,k Workshops of the most recent years. The ,k mailing list contains about 1700 e-mail addresses from across the world, and all the important information about a variety of activities of the network is distributed across this list on a daily basis. The "Scientific Highlights" of the ,k newsletters reflect the scientific activities of the network and aim at presenting reviews and current developments in the field. This special issue of physica status solidi (b) gives a collection of some of the most recent Highlight contributions to the ,k newsletter. All manuscripts originally posted on the ,k server were peer-reviewed by two referees and accepted according to the standards of pss. They are published here partly in revised or updated version. We hope that the readership of the journal will benefit from the quality of the research they report on and the high level of the presentations.
