Spontaneous transverse EMF in inelastic scattering of quasi-two-dimensional electrons

We calculate the spontaneous transverse electric fieldE y which arises in a quasi-two-dimensional superlattice in a strong driving electric fieldE x when the electron energy spectrum is nonadditive. The interaction of electrons with nonpolar optic phonons is taken into account. The stability of nonzero values ofE y is determined from examination of the minimum in the synergy potential. The temperature dependence of the critical fieldE xc (the bifurcation point) is determined, and the voltage—current curves are determined.
