Lateral 2D superlattices in GaAs heterostructures with independent control of carrier density and modulation potential

D. Q. Wang, D. Reuter, A. D. Wieck +2

We present a new double-layer design for 2D surface superlattice systems in GaAs-AlGaAs heterostructures. Unlike previous studies, our device (1) uses an in-situ gate, which allows…
