Electrical characteristic of amorphous indium gallium zinc oxide (a-IGZO) thin film transistors (TFTs) on flexible substrate are investigated with various channel width and length. Its electrical properties according to the physical dimension of the channel are analyzed through Technology Computer-Aided Design (TCAD) simulation. Index Terms — Density of states (DOS), flexible, In-GaZn-O (IGZO),...

This paper presents further results and extensions of our previous point defect model for time-dependent growth of passive oxide films on metal surfaces. Specifically, by accounting for vacancies as material species rather than just holes in the oxide lattice, the model incorporates more plausible expressions for interfacial reactions and associated kinetic rate expressions. We use the model to...

Nickel oxide thin films have been widely studied as an optical active layer in electrochromic devices. It is well known for these films that thermal treatment is the key factor which determines the electrochromic effect during potential cycling. Therefore, it is extremely important to perform thermal analysis on the thin films rather than on the corresponding xerogels. In this article, the ther...

We report direct observation of a "Pac-Man" like coarsening mechanism of a self-supporting thin film of nickel oxide. The ultrathin film has an intrinsic morphological instability due to surface stress leading to the development of local thicker regions at step edges. Density functional theory calculations and continuum modeling of the elastic instability support the model for the process.

Using dielectric-constant (ε) matching of metal-oxide (MO) with Ag film, highly transparent MO/Ag electrodes are demonstrated. At the large-ε MO/Ag interface, surface-plasmon was suppressed and the film showed increased optical-transmittance (>70%). OLEDs fabricated using large-ε MO/Ag electrodes show 1.38 times greater luminance than that of devices with small-ε MO/Ag.

BACKGROUND: Biotechnology applications of magnetic gels include biosensors, targeted drug delivery, artificial muscles and magnetic buckles. These gels are produced by incorporating magnetic materials in the polymer composites. METHODS: A biocompatible magnetic gel film has been synthesized using polyvinyl alcohol. The magnetic gel was dried to generate a biocompatible magnetic film. Nanosized ...

A gradient Si-rich oxide multilayer (GSRO-ML) deposition structure is proposed to achieve super-high density Si quantum dot (QD) thin film formation while preserving QD size controllability for better photovoltaic properties. Our results indicate that the Si QD thin film using a GSRO-ML structure can efficiently increase the QD density and control the QD size. Its optical properties clearly pro...
