Abstract
This project proposes design, construction and demonstration of a new type of thin-film transistor (TFT), based on indium phosphide compound semiconductors. Models predict unity power gain and unity current gain (fT and fmax) above 10 GHz for the new TFTs in a polycrystalline form compatible with large-area deposition & patterning on flexible metal foils or polymer sheets, using low cost, large (> 1 um) feature sizes. These TFTs should eventually outperform the best high-cost, single-crystal silicon or gallium arsenide transistors at the same feature size and temperature.
