Abstract

We have studied the low-field magnetoresistance of the two-dimensional electron gas in GaAs/<m1;&33>AlxGa1-xAs in the presence of a two-dimensional lateral surface superlattice (2D LSSL) potential, and observed, for the first time, the guiding-center drift resonance, previously reported for one-dimensional LSSL structures. The 2D LSSL potential is created by applying a voltage Vg to a 200 nm period grid-gate structure fabricated on top of the sample and can be tuned continuously from being repulsive to attractive by tuning Vg.
