Abstract
This chapter explores the DR in the doping superlattices of HD nonlinear optical semiconductors based on a newly formulated electron dispersion relation considering all types of anisotropies of the energy band spectrum within the framework of k.p formalism in the presence of Gaussian band tails under magnetic quantization. We have also investigated the magneto DRs in doping superlattices of HD III–V, II–VI, IV–VI and stressed Kane type semiconductors respectively. The DOS functions for all the materials in this case are series of non-uniformly distributed Dirac’s Delta functions at specified quantized points in the respective energy axis. The spacing between the consecutive Delta functions is functions of energy band constants and quantization of the wave vector space of a particular material. The DOS function needs two summations namely one summation over the Landau quantum number and the other one is due to mini band index. Section 11.4 contains 5 open research problems, which form the integral part of this chapter.
