Abstract In this chapter, we study the carrier statistics (CS) in quantized extremely
degenerate III–V, ternary, quaternary and tetragonal compounds respectively. We
have also investigated the influence of photo-excitation and electric field on the Fermi
energy. We note by taking various types of opto-electronic materials as examples that
the Fermi energy oscillates with inverse magnetic field due to SdH effect, changes
with changing electric field, light intensity, wave length and alloy composition in
different ways which are totally energy band constants dependent.

1 Introduction
Ghatak et al. for the last forty years have investigated extensively the various band
structure-dependent electronic properties of various semiconductors and their quantized counter parts under different physical conditions which are being reflected by
circa 14 research monographs and more than 300 research publications of the said
group, a brief cross section of which is given in [1–80]. A look at their research
