Paper Abstract

In this paper we have studied the thermoelectric power in quantum wells, quantum wires and quantum dots of laser and fiber optic materials within the framework of k.p formalism by deriving the respective electron energy spectra in the presence of crossed electric and magnetic fields respectively. It is found, taking n—Cd3P2, as an example, that the same power decreases in various manners with increasing electron concentration, decreasing magnetic field arid decreasing film thickness respectively. The theoretical results are in quantitative agreement with the experimental observations as reported elsewhere. In addition, the corresponding expressions for three—band Kane model, two—band Kane model and that of parabolic models fiber optic and laser materials have been obtained as special cases of our generalized analysis.
