Abstract

Scanning tunneling microscopy is now well established as a powerful technique for surface structural studies. Our aim is to demonstrate how this technique might also become useful for the spectroscopy of surfaces, and in particular of surface electronic states. We do this by direct calculation of the tunneling current flowing into, or out of, a graphite surface, as a function of an applied voltage V, illustrating the direct relationship between the current J(V) and the surface electronic structure at energy E-E//F equals V. Graphite has been chosen because it is an important surface, with perfectly known atomic structure, and a simple and well-known electronic structure, where localized sigma and pi states coexist with fairly delocalized interlayer bulk states, and with recently discovered empty surface states.
