Density of states in a two-dimensional electron gas in the presence of a one-dimensional superlattice potential

Journal Article


Abstract


  • Magnetocapacitance measurements are performed on a holographically microstructured AlxGa1-xAs-GaAs heterostructure, in order to obtain direct information about the density of states of a periodically modulated two-dimensional electron gas. Comparison with microscopic calculations shows that the observed pronounced modulation of the magnetocapacitance oscillations has the same origin as the novel resistance oscillations recently reported for this system. © 1989 The American Physical Society.
