Abstract

Transport phenomena in a double-bend quantum structure fabricated in the two-dimensional electron gas of a modulation doped GaAs/AlGaAs structure, are studied experimentally. The structure consists of an electrostatically defined quantum dot with two one-dimensional wires connected on opposite corners of the dot. The current-voltage characteristics of such devices exhibit quantized conductance breakdown (non-linear behavior), conductance variation with confinement, and non-linear and asymmetric behavior at high bias condition. Low temperature conductance of this structure shows evidence of resonant tunneling, while the peaks of the conductance vary with temperature.
