Chemical Force Microscopy Enables a New Look on Surfaces
Abstract As the surface functionality is gaining more and more relevance in modern surface technology, the need for an analytical tool with chemical sensitivity and high lateral resolution is becoming important more than ever. In this article, we introduce the novel method "Chemical Force Microscopy" (CFM), which is enabling the chemical mapping of the surface with nm-resolution for the first time. This method has proved to be efficient to optimise and understand different processes on industrial surfaces. In the fields like plasma, coating, cell biology, pharmaceutical and printing technologies, this method has shown to be supremely efficient. [source]

High Definition Digital Fabrication of Active Organic Devices by Molecular Jet Printing,

ADVANCED FUNCTIONAL MATERIALS, Issue 15 2007
J. Chen
Abstract We introduce a high resolution molecular jet (MoJet) printing technique for vacuum deposition of evaporated thin films and apply it to fabrication of 30,,m pixelated (800,ppi) molecular organic light emitting devices (OLEDs) based on aluminum tris(8-hydroxyquinoline) (Alq3) and fabrication of narrow channel (15,,m) organic field effect transistors (OFETs) with pentacene channel and silver contacts. Patterned printing of both organic and metal films is demonstrated, with the operating properties of MoJet-printed OLEDs and OFETs shown to be comparable to the performance of devices fabricated by conventional evaporative deposition through a metal stencil. We show that the MoJet printing technique is reconfigurable for digital fabrication of arbitrary patterns with multiple material sets and high print accuracy (of better than 5,,m), and scalable to fabrication on large area substrates. Analogous to the concept of "drop-on-demand" in Inkjet printing technology, MoJet printing is a "flux-on-demand" process and we show it capable of fabricating multi-layer stacked film structures, as needed for engineered organic devices.

Abstract In this Progress Report we provide an update on recent developments in inkjet printing technology and its applications, which include organic thin-film transistors, light-emitting diodes, solar cells, conductive structures, memory devices, sensors, and biological/pharmaceutical tasks. Various classes of materials and device types are in turn examined and an opinion is offered about the nature of the progress that has been achieved. [source]
