摘要：

Electron transport along the growth axis of a series of slightly indirect GaAs/AlAs superlattices (SL) is experimentally investigated. Our results, based on current-voltage and frequency resonance measurements in agreement with calculated characteristics, reveal unambiguously the existence of negative differential velocity at 80 K. Miniband transport in the lower Xxy miniband appears to explain this effect, owing to the low effective mass of Xxy states along the quantization axis. (C) 1994 American Institute of Physics.
