Wide Bandgap Semiconductors and Ultaviolet LEDs

 Leo J. Schowalter, CTO
Description: Importance of new semiconductor materials and devices for modern civilization. Electronics industry is now the largest industry in the US. Wide Bandgap Semiconductors: larger energy gap allows higher power and temperature operation and the generation of more energetic photon; the 3-nitrides (AIN, GaN and InN), SiC have recently become feasible. Overview of the Laser Diode Market, the Water Treatment Market and an discussion of semiconductor technologies and LED fabrication.
