Transport and scattering in a lateral surface superlattice are investigated. A Monte Carlo calculation of the drift velocity versus electric field, using simple sinusoidal energy bands in two dimensions, shows negative differential mobility. The negative differential mobility is the result of Bloch oscillations, as is apparent from oscillations in the velocity autocorrelation function.
