Paper Abstract

In this paper, an attempt is made to investigate the photoemission from III-V, II-VI, pbTe/SnTe, strained layer and HgTe/CdTe superlattices with graded structures under magnetic field and compare the same with the bulk specimens of the constituent materials by formulating the respective magnetic-dispersion relations. It is found, that the photoemission exhibits oscillatory dependence with inverse quantizing magnetic field and the electron concentration respectively in all the cases. The oscillations in HgTe/CdTe superlattices show up much more significantly as compared to other systems even in the presence of broadening. In addition, the well-known expressions for the bulk specimens of non-degenerate parabolic materials have also been derived as special cases from our generalized expressions.
