We have performed quantum-mechanical as well as classical magnetotransport calculations for a lattice of antidots with additional barriers. Both approaches reproduce the experimentally observed well-known commensurability peaks simultaneously with a negative differential magnetoresistance. By comparing both calculations, we find that quantum interference leads to an enhancement of the latter ...
