Polymer Surface Viscoelasticity Affects Organic Thin-Film Transistor Performance [Research]
Thin polymer films exhibit glass transition temperatures (Tgs) that are depressed from the bulk material Tg because of increased degrees of chain motion. Using such films as gate dielectrics in organic thin-film transistors provides a sensitive new probe of polymer surface motional characteristics at the buried semiconductor-dielectric interface. Researchers at Northwestern University’s Materials Research Science & Engineering Center find that pentacene thin-film transistor mobility depends dramatically on the pentacene growth temperature on the polymer dielectric.

High-performance Transparent Inorganic-organic Hybrid Thin-film n-type Transistors [Research]
Thin-film transistors, already indispensable in a number of portable electronics, would benefit from optical transparency and compatibility with flexible, lightweight plastics.
Transistors with these qualities would be a major advance if they could be fabricated by a scalable, large-area process.

Structural and Morphological Control of Multifunctional Oxide Nanostructures at Multi-dimensions [Research]
Oxide ceramics are ubiquitous in modern society- ranging from capacitors in electronic gadgets to high-tech displays. In numerous future technologies, it is necessary to “pattern” ceramic oxides in various forms, e.g., dots and lines, at the nanometer scale.
NU-MRSEC researchers Zixiao Pan, Suresh K. Donthu and Vinayak P. Dravid have demonstrated successful fabrication of single crystalline […]

IRG1, Synergistic Linear and Nonlinear Phenomena in Multifunctional Oxide Ceramic Systems
The reduced size of materials with controlled internal structure (i.e., grain size, crystal orientation, etc.) leads to novel, unexpected phenomena and a very broad spectrum of technologically significant properties. In view of this scientific appeal and technological implications, we have developed […]
