Abstract

A pair of interdigitated gates, interlacing off center, is used to generate a widely tunable one-dimensional lateral superlattice in the two-dimensional electron gas at a GaAs/AlGaAs heterointerface. Magnetotransport measurements with statically biased gates demonstrate that the conduction-band modulation is strongly influenced by higher harmonics, thus allowing the realization of both symmetric ...
