Abstract

We present experimental and theoretical results on magnetoresistivity oscillations of high-mobility two-dimensional electron systems in a weak superlattice potential. Experimentally, the band conductivity of a sample with a holographically produced grid potential is shown to be considerably smaller than that of the same sample with a similar linear grating potential of the same lattice ...
