Abstract
A simple model is presented to investigate the effect of the size of the tip in a scanning tunneling microscope on the image of graphite. In the model, the tip and carbon atoms of the surface of graphite are replaced by circles with areas effective to the local tunneling currents. It is shown that the STM images reflect the hexagonal arrangement of carbons but differ depending on the size of the tip.Keywords
