Abstract
The profile is calculated for photogenerated nonequilibrium electron concentration in thickness of a three-layer film -MCT structure in crossed electric and magnetic fields, in which the band gap of the central region is constant, but increases in adjacent variband regions. It is shown that a three-layer structure with variband regions can be replaced by a homogeneous film via introducing effective surface generation and surface recombination velocities at boundaries of central and variband regions.
