✦ Synopsis

We compute the distribution of the conductance PðGðT; V ÞÞ of a one-dimensional (1D) disordered wire non-perfectly coupled to leads (dirty contacts) at finite temperature T and bias voltage V. At regimes of temperatures and/or bias voltages larger than the mean level spacing, we show that the conductance distribution can be accurately represented by a finite number of convolutions of the distribution pðg c Þ of the conductance g c at zero temperature and zero bias voltage.
