摘要：

The angular distribution of the phonon emission from a heated two-dimensional electron gas in a strong magnetic field is studied. It is shown that for processes involving inter-Landau level transitions a simple decoupling approximation is sufficient in treating the disorder; intra-Landau level processes are, however, seen to require more careful treatment and an analysis using the self-consistent Born approximation is given.
