A THEORY OF VACUUM TUNNELING MICROSCOPY1
A theory for tunneling between a real surface and a model probe tip, applicable to the "scanning tunneling microscope" is presented. The tunneling current is found to be proportional to the local density of states of the surface, at the position of the tip. It can be shown that the tunneli...

| Summary: | A theory for tunneling between a real surface and a model probe tip, applicable to
the "scanning tunneling microscope" is presented. The tunneling current is found to
be proportional to the local density of states of the surface, at the position of the tip.
It can be shown that the tunneling conductance has exponential dependence on the
distance of the nearest approach to the surface |
