中文摘要 | We use the 2D quantum percolation model to simulate the mesoscopic transport properties of disordered metallic films. The conductance of a mesoscopic sample is calculated by the multichannel Landauer formula, with the transmission and reflection coefficients evaluated numerically with a recursive Green-function approach. The distribution of the conductance is found to exhibit three distinct types: normal, log-normal and between normal and log-normal, depending on the sample size L and metal fraction p. The variation of the mean with L yields the localization length and the root-mean-square conductance fluctuation DELTA-g is shown to have different regimes, including the universal-conductance fluctuation regime where DELTA-g is constant as a function of L and of the order of e2/h. Based on these results, we propose the use of mesoscopic samples of disordered metallic films for the direct experimental observation of Anderson localization for electrons. Two possible sample systems are discussed. |
