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 ...

Metal-oxide thin-film transistors (TFTs) have shown increasing utilization in a wide range of applications. However, without a p-type inversion layer or controllable p-type doping mechanism 1,2,3 ...

As a result, the inversion layer no longer remains, and the forward drain current flow is blocked. ... and relatively fast recovery body diode 500- to 650-V rated power MOSFETs, ...
