Abstract
The heating of electrons in an AlxGa1-xAs/GaAs (x>0.42) heterostructur e in a lateral (directed along the heterointerfaces) electric field is studied. Population inversion on the size-quantization subbands of th e Gamma valley of GaAs and a giant population inversion between the X- valley states of AlxGa1-xAs and Gamma-valley states of GaAs are pre di eted. The possibility of using these inversions for achieving stimulat ed IR emission is discussed. (C) 1998 American Institute of Physics.
