High transparent conductive indium tin oxide/titanium dioxide (ITO/TiO2) nanostructured thin film is prepared by sol-gel dip-coating technique. This method yielded monodisperse ITO nanoparticles with mean diameter of 12 nm. The atomic composition of the Sn within the ITO structure changed from 0-20 wt.%. Through controlled annealing temperature at 550 oC, the result...

A new current-programming pixel circuit for active-matrix organic light-emitting diode (AM-OLED) displays, composed of four organic thin-film transistors (OTFTs) and one capacitor, has been designed, simulated and evaluated. The most critical issue in realizing AMOLED displays with OTFTs is the variation and aging of the driving-TFTs and degradation of OLEDs. This can cause image sticking or de...

Fabrication of microporous structures for the anode of a thin film solid oxide fuel cell (SOFC(s)) using controlled etching process has led us to increased power density and increased cell robustness. Micropores were etched in the nickel anode by both wet and electrochemical etching processes. The samples etched electrochemically showed incomplete etching of the nickel leaving linked nickel isl...

Recently, biological materials such as DNA molecules, proteins, and albumen have been extensively investigated for various applications, as they are environmentally friendly and exhibit novel optical and electronic properties. Especially, over the last decades, DNA–lipid complex have been frequently reported as components of optical electronic devices. In this mini-review, the physicochemical p...

Thin film coatings have been essential in development of several micro and nano-scale devices. To realize thin film coatings various deposition techniques are employed, each yielding surface morphologies with different characteristics of interest. Therefore, understanding and control of the surface growth is of great interest. In this paper, we devise a novel network-based modeling of the growt...

This paper presents an energy-harvesting system consisting of amorphous-silicon (a-Si) solar cells and thinfilm-transistor (TFT) power circuits on plastic. Along with patterned planar inductors, the TFTs realize an LCoscillator that provides power inversion of the DC solarmodule output, enabling a low-cost sheet for inductivelycoupled wireless charging of devices. Despite the low performance of...

This chapter aims to provide the reader with a practical knowledge about electrical methods to measure organic thin film transistor devices. It presents a series of recipes, which allow the experimentalist to gain insight into the performance and limitations of the devices and circuits being measured. It also gives guidelines on how to correctly interpret the measurements and to provide feedbac...

An important objective of software fault tolerant systems should be to provide a fault-tolerance infrastructure in a manner that minimizes the effort required by the application developer. In the limit, the objective is to provide fault tolerance transparently to

We study the sewing constraints for rational two-dimensional conformal field theory on oriented surfaces with possibly non-empty boundary. The boundary condition is taken to be the same on all segments of the boundary. The following uniqueness result is established: For a solution to the sewing constraints with nondegenerate closed state vacuum and nondegenerate two-point correlators of boundar...
