Sažetak
An attempt is made to investigate the effective electron mass in degenerate II-VI semiconductors, taking n-CdS as an example, under different physical conditions. We have formulated the effective electron masses in 3D, 2D and 1D configurations, respectively. We have plotted the effective mass with various physical variables. It is found that the effective masses vary with magnetic and size quantum numbers under different conditions due to the splitting of the two spin states by the spin-orbit coupling and the crystalline field. The corresponding results for parabolic semiconductors have also been derived as special cases of the generalized expressions.
