Abstract

Analysing the conductance fluctuations observed in low-temperature magnetoresistance, we study electron wave interference effects in the quasi-ballistic transport regime of a narrow wire, defined by split metal gates, on the two-dimensional electron gas of a GaAs/AlGaAs heterojunction. There is a clear difference in the conductance fluctuations between short and long wires of 2 and 6 μm gate length, respectively. Such a difference can be explained by considering whether some correlated channels exist in the wire or not.
