Abstract
Lateral superlattices have been fabricated on AlGaAs parabolic quantum wells. Two electrical subbands occupied in the growth direction lead to two sets of classical commensurability oscillations, each characterized by a different Fermi velocity. The dominant features can be explained by combining quantum-mechanical subband occupation and classical commensurability oscillations. The potential modulation of the lateral superlattice can be tuned by the nanopatterned top gate as well as by a back gate electrode.
