The transport and switching of Xe atoms on the Ni-W interface of a scanning tunnelling microscope

The transport and switch of Xe atoms on the Ni-W interface of a scanning tunnelling microscope have been analysed for different geometries as a function of the tip position with respect to the Ni(110) surface. Our results show that the control of the different experimental results can only be achieved by a precise control of the position of the tip on the sample. In particular, the tip-sample Xe switch can only be obtained within tip heights of 0.2Å.
