摘要：

We have studied square two-dimensional lateral surface superlattices of period 100 nm formed by shallow etching of holes into a GaAs/AlGaAs heterostructure. In some samples, the symmetry was broken using piezoelectric modulation. The commensurability oscillations in the magnetoresistance characteristics of our samples were fully in accord with a recent semi-classical model of guiding center drift in two-dimensional superlattices.
