Transverse thermo-magnetic effect in double-periodic semiconductor superlattice at the lack of inversion symmetry

The surface density of charge current in two-dimensional double-periodic n-type semiconductor superlattices is calculated the one-electron approximation an external magnetic field presence a temperature gradient. was assumed to be constant, uniform, applied perpendicular plane electron gas. joint solution Schrodinger equation and kinetic Boltzmann shown that dependence transverse about module gradient are significantly non-linear nature, there areas with negative differential conductivity. relaxation time on quasi-momentum taken into account model phenomenologically through dispersion law carrier subbands. At lack inversion symmetry laws subbands not even functions quasimomentum defined Brillouin zone. As result, thermo-magnetic increases many times comparison symmetric case Keywords: effect, doubly periodic superlattices.
