Abstract

in this paper we study the Einstein relation in superlattices of wide-band gap semiconductors under crossfield configuration and the forming materials incorporating spin and broadening of Landau levels, it is found, taking GaAs/ALAs superlattice as an example that the diffusivity-mobility ratio increases with increasing electron concentration and oscillates with inverse quantizing magnetic field due to SdH effect. Thetheoretical analysis is in agreement with the suggested experimental method of determining the same ratio in degenerate materials having arbitrary dispersion laws.
