Abstract
The effect of wire width variation on the conductance of a 1 μm×30 nm silicon quantum wire has been studied. Both resonant tunneling features and conductance fluctuations superimposed on the quantized steps have been observed and explained by the existence of a step-wise constriction in the wire due to the nonideality in the fabrication process.
