Abstract—A novel technology for manufacturing high-performance
hydrogenated amorphous silicon (a-Si:H) thin-film
transistors (TFTs) is developed in this letter. In the bottom gate
light-shield a-Si:H TFT structure, the side edge of a-Si:H island
is capped with extra deposition of heavily phosphorous-doped
a-Si layer. Such an ingenuity can effectively eliminate the leakage
path between the parasitic contacts of source/drain metal and the
sidewall of a-Si:H island edge. In addition, electrical performance
of the novel a-Si:H TFT ....etc

Crystalline-Silicon Solar Cells for the 21st Century


ABSTRACT
The worldwide market share for crystalline-silicon solar cells has
increased steadily in the last 10 years. In 1998, about 87% of the
photovoltaic modules shipped worldwide are based on crystalline
silicon. This dominance will likely continue into at least the first few
years of the 21st century. The long-term growth of crystalline-silicon
solar cells will depend on the development of low-cost ....etc

A SONOS memory cell is formed from a standard polysilicon NMOS transistor with the addition of a small sliver of silicon nitride inserted inside the transistor's gate oxide. The sliver of nitride is non-conductive but contains a large number of charge trapping sites able to hold an electrostatic charge. The nitride layer is electrically isolated from the surrounding transistor, although charges stored on the nitride directly affect the conductivity of the underlying transistor channel. The oxide/nitride sandwich typically consists of a 2 nm thi ....etc

Abstract:
Amorphous computing consists of a multitude of interacting computers with modest computing power and memory, and modules for intercommunication. These collections of devices are known as swarms. The desired coherent global behavior of the computer is achieved from the local interactions between the individual agents. The global behavior of these vast numbers of unreliable agents is resilient to a small fraction of misbehaving agents and noisy and intimidating environment. This makes them highly useful for sensor networks, MEMS, inte ....etc

In metallic alloys at room temperature, atomic diffusion is typically very sluggish, and equilibrium or metastable phases do not undergo transformations. However, during plastic deformation, significant atomic mobility is possible. In addition, deformation may lead to mixing, possibly favoring the formation of nonequilibrium phases. In this talk, two examples will be presented, in which the rate of transformation to equilibrium is enhanced by mechanical deformation. In an unstable, nanocrystalline Fe50Cu50 solid solution, ball milling leads to ....etc
