Angle Deposition (angle + deposition)
Selected AbstractsStructured Ti/Hydrocarbon Plasma Polymer Nanocomposites Produced By Magnetron Sputtering with Glancing Angle DepositionPLASMA PROCESSES AND POLYMERS, Issue 1 2010Andrei Choukourov Abstract Structured Ti/hydrocarbon plasma polymer nanocomposite films are deposited at a glancing angle by magnetron sputtering of titanium in an Ar/hexane mixture and by sequential magnetron sputtering of titanium and polypropylene. The surface chemistry of such films is tuned by adjusting the gas mixture composition. The structure of the substrate may convert the morphology of organic films deposited at a glancing angle from continuous to nanostructured thin films. [source] Embedding Ag Nanoparticles into MgF2 Nanorod Arrays,ADVANCED FUNCTIONAL MATERIALS, Issue 11 2008Yuping He Abstract Using a unique glancing angle co-deposition technique, face-centered cubic Ag nanoparticles have been embedded into aligned polycrystalline MgF2 nanorods with different topological shapes, such as tilted, zigzag, vertical, and helical nanorods. The optical properties of the artificial nanocomposite materials, such as surface plasmon resonance and polarization absorbance, are determined by the size of the Ag nanoparticles as well as the alignment and shape of the MgF2 nanorod arrays. The combination of co-deposition and glancing angle deposition provides a unique way to design novel nanocomposite materials and doped nanorod arrays. [source] Nanotube Arrays: Morphology Control of Nanotube Arrays (Adv. Mater.ADVANCED MATERIALS, Issue 29 200929/2009) On p. 2983 Michael J. Brett and co-workers demonstrate a template-directed technique to produce arrays of silicon nanotubes (SiNTs) with highly engineerable morphology. Fabrication steps include glancing angle deposition (GLAD) of the templates, low-pressure CVD of a shell-Si coating, ion milling to expose the templates, and wet-chemical etching for removal of the templates. The technique may be generally adapted to a wide variety of morphologies and NT materials. [source] Morphology Control of Nanotube ArraysADVANCED MATERIALS, Issue 29 2009Zhifeng Huang Arrays of silicon nanotubes (SiNTs) with controllable architectures, wall thicknesses and crystallinity are fabricated by a new template-assisted technique. The method includes a sequence of glancing angle deposition of the templates, low-pressure CVD shell-Si coating, ion-milling to expose the templates, and wet-chemical etching for template removal. The technique may be generally adapted to a wide variety of morphologies and NT materials. [source] Morphology in-Design Deposition of HfO2 Thin FilmsJOURNAL OF THE AMERICAN CERAMIC SOCIETY, Issue 10 2008Ni Jie We investigated factors influencing the growth morphology of hafnium dioxide (HfO2) thin films by glancing angle deposition, and found that a shape factor defined as the ratio of the deposition rate over the substrate rotation speed played a key role in determining the morphology of the films. By adjusting this factor, we fabricated successfully films of aligned HfO2 nanorods, nanosprings, and nanohelix. Comparing with the flat films, these nanostructured films exhibited enhanced light transmittance and photocatalytic activity in hydrogen production from water splitting under ultraviolet radiation.
