Abstract
We study a novel surface superlattice structure formed by a honeycomb gate pattern on GaAs/AlGaAs heterostructures with a high-mobility two- dimensional electron gas. The hexagonal gate arrays, fabricated by ele ctron beam lithography, had pitches as small as 150 nm, corresponding to hexagons with 87 nm between adjacent vertices. Magnetoresistance me asurements show features which reflect the presence of the induced hex agonal superlattice potential.
