摘要：

The Schrödinger equation in the tight-binding approximation is solved numerically with the method of conjugate gradients to study the phase mismatching effect on the scattering of electrons off a screw dislocation. When an electron beam strikes on a screw dislocation, there appears in the down stream a semi-infinite plane on which the amplitude of electronic wave is reduced appreciably. © 1979 Springer-Verlag.
