Abstract
Numerical calculations of conductance in an atom-sized contact between an STM-tip and a metal surface have been performed within the framewo rk of the tight-binding model. In order to take into account the const ricted structure of the point contact, the scattering region was intro duced in the model. Based on the results of the calculations, the effe ct of the scattering potential on the conductance quantization is disc ussed.
