Sažetak
An attempt is made to investigate the Einstein relation for the diffusivity-mobility ratio of the carriers in quantum well wires of A113BV2 semiconductors, taking n-Cd3P2 as an example. On the basis of a newly derived E - kz dirpersion relation of the carriers, which includes various types of anisotropies in the energy spectrum, it is found that the above ratio increase with increasing electron concentration. In addition, the corresponding results of parabolic semiconductors are also obtained from the expressions derived.
