✦ Synopsis
We discuss electron transport through a semiconductor superlattice subject to an electric field parallel to, and a magnetic field perpendicular to, the growth axis using a semiclassical balance equation model. We find that the current-voltage characteristic becomes multistable in a large magnetic field; furthermore, hot electrons display novel features in their current-voltage characteristic, including absolute negative conductivity and a spontaneously generated dc current at zero bias.
