Abstract
We analyze recent measurements of the room temperature current-voltage characteristics of gold nanowires, whose zero current conductance is quantized in units of 2e(2)/h. A faster than linear increase of curren t with voltage was observed at low voltages beginning from V-c = 0.1 V . We analyze the nonlinear behaviour in terms of a dynamic Coulomb blo ckade of conducting modes and show that it may be explained as a Lutti nger-liquid effect. (C) 1998 Academic Press Limited.
