J. E. Cunningham, W. Y. Jan, "Carrier Sweep-Out from Quantum Wells in an Electric
Field" OSA Proceedings on Picosecond Electronics and Optoelectronics, 9,
210-213, (1991). Shows that the carrier sweep-out from GaAs/Al/sub x/Ga/sub
1-x/As quantum wells with xless than or=0.3 is thermally assisted at low fields, and dominated by tunneling at high fields |
