Abstract

Energies and wavefunctions of edge states in a two-dimensional electron gas are evaluated for a finite step potential barrier model. The spectrum exhibits richer structure than observed previously for an infinite barrier model. Surprisingly, instead of smooth Landau level bending in the vicinity of the barrier, the levels acquire a step-like form. These plateaus have a direct impact on the widths of the magnetotransport conducting channels.
