Abstract
An attempt is made to study the thermoelectric power of the electrons under strong magnetic quantization in HgTe/CdTe superlattices with graded structures and to compare the same with that of the constituent materials by formulating the respective expressions. It is found, that the thermoelectric power increases with decreasing electron concentration and increasing magnetic field, respectively, in an oscillatory manner due to Shubnikov-de Haas effect. In addition, the well-known expressions for bulk specimens of parabolic energy bands have been derived under certain limiting conditions from our generalized relations.
