文摘
- •
Nonparabolicity effects modelled with 4th order Schrodinger equation derived from 14 bands kp method.
- •
Effects of external magnetic field modelled through second order perturbation theory.
- •
First order corrections for the wavefunction included, which allows dependence of dipole matrix element on magnetic field.
- •
Application of the model on experimentally achieved QCLs and generalization of existing models.
