The combination of black silicon to improve the light absorption and negatively charged alumina to form an induced collecting junction characterizes a photodiode with external quantum efficiency ...

The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley ...

Peak impact power 300 KW, energy loss up to 150 J with single impulses. High-voltage impulse diode-thyristors. High-voltage impulse diode-thyristors can be produced via 4-layer thyristor elements with ...

Diode Approach has had fundamental problems but adding a second insulator layer could help The power conversion efficiency of broadband antennas, log-periodic, square-spiral, and archimedian-spiral ...
