摘要
We have derived the expression of the spectral density for the current shot-noise in terms of the nonequilibrium Green's functions( closed-path Green's functions) for a. one-dimensional mesoscopic junction, and performed numerical calculations to discuss the dependence of the zero frequency spectral density for the currentshot-noise on other variables when the tunnling junction is pure or impure.
