We review the modeling techniques for mid-infrared quantum cascade lasers based on III/V materials, clarifies or corrects ambiguity concepts such as state-dependent effective mass, the non-parabolic kinetic energy and its modeling, and the polarized waveguide confinement in the mathematical perturbation sense.

The spin of electrons in silicon quantum dots has been a promising candidate for qubits for quantum computing applications in recent years, demonstrating long coherence time due to its weak spin-orbit coupling and the existence of stable zero nuclear spin isotopes. However, a fundamental challenge is the degeneracy of the conduction band minima, which is a decoherence source. The realization of atomically flat Si/SiGe heterostructures which can potentially solve the small valley splitting issue in Si/SiGe quantum dots applications motivated this work.
