State-density oscillations of two-dimensional electrons in a transverse magnetic field
Shklovskii B. I., Efros A. L.
A theory is derived for the nonlinear screening by a two-dimensional electron gas of the potential of charged impurities distributed at random in a volume. This theory is used to derive the position of the Fermi level and the width of the state-density peak at the Landau level as functions of the electron density in a magnetic field.
