1959 A. L. McWhorter & R. H. Rediker in Proc. IRE 48 1207/1 The cryosar is a new semiconductor device, intended primarily for high-speed computer switching and memory applications, which utilizes the low-temperature avalanche breakdown produced by impact ionization of impurities. The name of the device was derived from ‘low-temperature (cryo-) switching by avalanche and recombination’.
1962 Solid State Electronics 5 301 Further ‘word’ and ‘digit’ selection by means of cryosars is proposed.
2001 K. Aoki Nonlinear Dynamics & Chaos in Semiconductors p. xi Many devices have been proposed in order to develop new, modern..oscillators and switching devices such as the ‘oscillistor’, the ‘cryosar’, and the Gunn diode.
