A. Geizutis et al., PICOSECOND SWITCHING DUE TO ELECTRON-TUNNELING AND AVALANCHE IN GAAS ALXGA1-XAS DIODE/, Electronics Letters, 34(14), 1998, pp. 1434-1436
A new semiconductor heterostrostructure diode with an S-type current-v
oltage characteristic that can be used for high-speed voltage switchin
g is proposed and demonstrated. This behaviour is caused by the electr
ons tunnelling through the potential barrier and initiating avalanche
multiplication in a small energy gap base region.
