Quasitwodimensional electron gas in a nonquantizing magnetic field and strong nonquantizing electric field
Abstract
A calculation is performed to determine the transverse electric field E_{y} formed in quasitwodimensional superlattices in a strong drift field E_{x} and a weak magnetic field that is perpendicular to the plane of the superlattice ( H‖OZ). When the electronic energy spectrum is nonadditive, the field E_{y} includes both the Hall factor and a spontaneous transverse electric field that exists whether H is present or not. The situation when the specimen is in a closed circuit with a resistor on the OY axis is examined. As the function E_{x}, the field E_{y} is multivalued (multistable) and variable. The stability of the branches of the function E_{y}(E_{x}) is determined using a specially introduced (kinetic) “potential” whose minimum corresponds to the steady state of a nonequilibrium electron gas.
