Abstract

The low temperature, high magnetic field phase of the two-dimensional electron system at the GaAs/GaAlAs heterojunction is distinguished by the appearance of both non-linear electrical conduction and a low frequency magneto-phonon branch with a small gap. The relationship between the gap and the threshold electric field for conduction is investigated and shown to be well accounted for by a simple model of a magnetically induced Wigner solid in a random field representing host disorder.
