Abstract

We analyze recent measurements of the room temperature current-voltage characteristics of gold nanowires, whose zero current conductance is quantized in units of $2 e^{2} / h$ . A faster than linear increase of current with voltage was observed at low voltages beginning from $V_{c} = 0.1$ V. We analyze the nonlinear behavior in terms of a dynamic Coulomb blockade of conducting modes and show that it may be explained as a Luttinger-liquid effect.
