Abstract

The density of electronic states of a two-dimensional electron gas in a perpendicular magnetic field is studied with both interband luminescence and cyclotron resonance experiments. Various oscillatory phenomena with a 1 B periodicity are observed, depending on the nature of scatterers which are outside the well or deliberately introduced in the middle of the two-dimensional layer.
