Sp. Mcalister et al., HYSTERESIS IN THE SWITCHING OF HOT-ELECTRONS IN INP INGAAS DOUBLE-HETEROJUNCTION BIPOLAR-TRANSISTORS/, Journal of applied physics, 76(4), 1994, pp. 2559-2561
The switching behavior of a composite-collector InP/InGaAs heterojunct
ion bipolar transistor is found to be hysteretic at temperatures below
200 K. This arises from the underlying S-shaped negative differential
conductivity associated with the hot-electron transport of electrons
across the heterojunction barrier in the collector structure of such t
ransistors.
