Abstract

We report on the observation of structures in the longitudinal resistance of a single two-dimensional electron gas (2DEG) in a perpendicular magnetic field at filling factor νcongruent with1±0.1. The observed structures can be switched off by depleting a second 2DEG, which is separated from the first by a 30 nm or a 60 nm AlGaAs-barrier, using a gate-electrode. Measurements as a function of ...
