摘要：

The carrier drift velocity versus applied electric field in GaAs/AlAs superlattices is directly determined from a photocurrent time of flight technique. The electron negative differential velocity regime is clearly evidenced and in good agreement with static current-voltage data in the case of a relatively thick barrier superlattice (7 AlAs layers). For a thinner barrier superlattice (4 AlAs layers) the low field electron mobility seems temperature dependent, and also a drastic hole mobility decrease is observed at low temperature and interpreted in terms of light hole freeze out. © 1990.
