摘要
Numerical calculations of conductance in an atom-sized contact between an STM-tip and a metal surface have been performed within the framework of the tight-binding model. In order to take into account the constricted structure of the point contact, the scattering region was introduced in the model. Based on the results of the calculations, the effect of the scattering potential on the conductance quantization is discussed.
