英文摘要	Perpendicular transport in a specially designed, doped and weakly coupled gaas/alas superlattice is investigated. a linear current-voltage at a bias within +/-10 mv and a negative differential velocity effect at a bias of about +/-40 mv are observed at low temperatures. the miniband conductance near zero electric field is studied as a function of temperature. it is found that the measured conductance increases slightly as the temperature increases to about 30 k, decreases as the temperature rises from 30 k to 70 k, and then increases strongly above 70 k, indicating the existence of a mobility gap.
