Abstract

The theoretical studies presented in this paper concern the influence of the atomic structure of the tip on the tunneling of electrons between the tip and the sample in STM. This problem has been discussed for the system formed by Al(001) surface and aluminium tip, where different geometries of the tip were taken into consideration. The obtained results have shown how various geometries of the tip induce considerably different STM images of the surface.
