Abstract
We examined discrete time-dependent changes in the conductance of a one-dimensional (1D) wire, due to a change in the scattering potential of a single defect, as a function of the width of the wire. We discovered that the discrete time-dependent changes are suppressed whenever a 1D subband is fully occupied. Our observations explicitly demonstrate that defect scattering and excess noise can be suppressed in a 1D wire.Keywords
