Influence of quantization of band states on the thermoelectric power in II–VI semiconductors

Summary An attempt is made to present a simplified analysis of the thermoelectric power in II–VI semiconductors in the presence of quantization of band states under different physical conditions. The thermopower decreases with increasing electron concentration in different manners, which is a direct consequence of band state quantization. We have plotted the thermopower with various other physical variables and the same power exhibits different types of oscillations in low-dimensions, respectively. The well-known results for parabolic energy bands have also been obtained as special cases of our generalized formulations under certain limiting conditions. In addition, the theoretical results are in quantitative agreement with the experimental data.
