Cryogenic Operation of Silicon Power Devices

The advent of low temperature superconductors in the early 1960's converted what had been a laboratory curiosity with very limited possibilities to a prac­ tical means of fabricating electrical components and devices with lossless con­ ductors. Using liquid helium as a coolant, the successful construction and operation of high field strength magnet systems, alternators, motors and trans­ mission lines was announced. These developments ushered in the era of what may be termed cryogenic power...
