CdS nanoparticles are II-VI group semiconductor in nature with suitable band gap for photoluminescence and photo-catalyst applications. CdS nanostructures were synthesized via a facile precipitation method in the presence of green capping agents such as starch, glucose, gelatin, salicylic acid in the green solvent of water. The influence of concentration, surfactant, precipitating agent on the ...

A novel technique to measure in situ, simultaneously, temperature and thin film thickness during semiconductor processing is described in this paper. The measurement technique is based on the principle propagating in a silicon wafer is a function of both the that the velocity of an ultrasonic Lamb wave wafer temperature and the thin film coating on the wafer surface. We are able to btain the pr...

Introduction to Thin Film Transistors reviews the operation, application and technology of the main classes of thin film transistor (TFT) of current interest for large area electronics. The TFT materials covered include hydrogenated amorphous silicon (a-Si:H), poly-crystalline silicon (poly-Si), transparent amorphous oxide semiconductors (AOS), and organic semiconductors. The large scale manufa...

The maximum entropy method (MEM) is widely used in research fields such as linguistics, meteorology, physics, and chemistry. Recently, MEM application has become a subject of interest in the semiconductor engineering field, in which devices utilize very thin films composed of many materials. For thin film fabrication, it is essential to thoroughly understand atomic-scale structures, internal fi...

We studied the magnetic properties of ferromagnetic-semiconductor composites based on nickel and porous-GaN, motivated by effort to couple semiconductor functionality. Nickel-infiltrated nickel-coated (laminated thin-film) porous GaN structures were fabricated electrodeposition, their subsequently examined collectively, vibrating sample magnetometry nanoscale, force microscopy. successfully dem...

Picene, which is an organic p-channel semiconductor and a component of superconductors, was derivatized with a thiadiazole-dioxide moiety to afford a novel acceptor molecule (PTDAO₂). PTDAO₂ can form stable anion radical species in solution and as a crystal, and its neutral crystalline thin film exhibits n-type transistor characteristics.

Dicyanomethylene-substituted quinoidal mixed oligomer was synthesized as a new soluble organic semiconductor, and OFET devices fabricated with a spin-coated thin film of showed ambipolar FET characteristics with electron and hole mobilities of 1.6 x 10(-2) and 7.0 x 10(-3) cm(2) V(-1) s(-1), respectively.
