Influence of band non-parabolicity on the oscillatory dependence of the Debye screening length in degenerate semiconductors on magnetic quantization

Abstract

The Debye screening length in degenerate non-parabolic bands is shown to have an oscillatory dependence on a quantizing magnetic field as in degenerate parabolic bands. The period of oscillations is, however, found to decrease with increasing non-parabolicity which also is observed to have no effect on the amplitude of the same.
