Magnetic Field Effects on Current Instability in a Weakly Modulated 2DEG

POSTER

Abstract

We have examined the collective excitation spectrum of a weakly modulated two dimensional electron magnetoplasma, analyzing the role of a steady current which induces drift instability. The inter- and intra-Landau band plasmon spectrum in quantizing magnetic field is derived within the self-consistent-field approximation with weak density modulation. In this, we determine the conditions on drift speed for the occurrence of magnetoplasmon instability.
