Abstract
We studied the effects caused by Joule heating in GaAs/AlAs superlattices. We measured the current-voltage characteristics of superlattice mesas of different cross sections. Each current-voltage characteristic showed a corresponding peak current followed by a region of negative differential conductivity, according to miniband transport in the superlattice. We found that Joule heating in the mesa ...
