Abstract

The dispersion law for electrons moving along a specularly reflecting boundary of a two-dimensional electron gas in the presence of a near-boundary potential well and a weak magnetic field is investigated theoretically. Numerical simulation is used to identify a number of features of the density of edge magnetic states that can be observed by magnetotransport and magnetooptics investigations. Ways to fabricate structures for studying these states are discussed. It is demonstrated that perfect-crystal interterrace boundaries can be created for a two-dimensional electron gas by introducing oblique slip planes into the heterostructure.
