Field Influence

We present a method of modeling of nonparabolic effects (NPE) in quantum nanostructures by using second order perturbation theory. We apply this model on multiple quantum well structures and consider the influence of external magneticfield on dipole matrix element which is usually considered constant. The dipole matrix element directly influences the optical gain, and our model can provide a better insight to how NPE and magnetic field influence the gain of quantum nanostructures.

Progressive Deterioration

Maintaining crystal quality during the growth of very thick multiple-quantum-wells is challenging due to the progressive deterioration in thick low-temperature barriers. The insertion of several high-temperature crystallinity restoring (CR) layers...
