The modification of the density of electron energy levels and conductivity due to random impurities in solids is investigated. The diagram perturbation method developed by Matsubara and Toyozawa for semi-conductor (referred to as M-T method) is employed in actual calculation. In order to estimate the accuracy of the M-T method, we compare it with other methods. Detailed discussions on the nature of various approximations are given and perfect correspondence between the M-T method and those by Edwards and by Klauder is established. It is concluded that the M-T method is the tractable best approximation. Numerical calculation for simplified model of three dimensional system is performed and some results are shown.
