Abstract

The authors have performed quantum-mechanical calculations of tunnelling current drained through a narrow probe weakly attached to quantum wires. The amplitude of the current is approximately proportional to the local density of states in the wires. They demonstrate that the spatial variation of the probability distribution of an electron due to quantum interference effects is obtained by scanning the probe along the wires.
