Samenvatting

The lateral photovoltage (LP) generated in a two-dimensional electron gas (2DEG) by a focussed laser spot has been shown to yield the potential distribution of a current carrying Hall-bar. The width of this distribution, which exhibits an abrupt change at even integer filling factors, is determined by the equilibration between the bulk and the edge states of the 2DEG. The effects of an anisotropic surface morphology and sample dimensions are reported.
