Abstract

The magnetoresistance of a two-dimensional electron gas (2DEG) subjected to a weak two- dimensional (2D) lateral superlattice potential is expected to reflect the peculiar self-similar energy spectrum of Bloch electrons in a magnetic field, i.e., the splitting of Landau levels (LL\'s) into sublevels. One experimentally established effect of a periodic potential is that the discrete LL\'s ...
