An eight-band quantum mechanical model of the electron and hole energy spectrum, in nanoscale semiconductor heterostructures with phenomenological boundary conditions for the charge carrier multicomponent effective wave function at the heterostructure interfaces, has been formulated using symmetry.
COMSOL programs based on this model were developed and used for design and simulation of mid-infrared quantum well diode lasers and intersubband/interband cascade lasers.
