We report on the effects of field-induced -X resonances on carrier transport and optical properties of GaAs/AlAs type-I short-period superlattices (SLs). We have observed an anomalously delayed photocurrent and 2-hh1 photoluminescence originating from X1-2 mixing. These observations clearly suggest
We report the observation of resonant tunneling and magneto-tunneling between states of different effective mass derived from zone centre ( ) and zone edge (X ) points of the Brillouin zone in single AlAs barrier diodes. The nature of the X states involved (longitudinal X z or transverse X xy ) is d
