摘要：

We investigate the nonlinear conduction mechanisms of electrons in a semiconductor superlattice miniband. Experimental results obtained from time-of-flight measurements in GaAs/AlAs superlattices are compared with analytical semiclassical approaches. It is shown that the peak velocity can be accounted for when electron heating is assumed to take place. The dynamics of electron transport is also investigated by numerically solving the time-dependent Boltzmann equation including polar optical phonon and interface roughness scattering.
