Conductance of a STM contact on the surface of a thin film
The conductance of a contact, having a radius smaller than the Fermi wave length, on the surface of a thin metal film is investigated theoretically. It is shown that quantization of the electron energy spectrum in the film leads to a step-like dependence of differential conductance G(V) as a funct...

| description |
The conductance of a contact, having a radius smaller than the Fermi wave length, on the surface of a thin
metal film is investigated theoretically. It is shown that quantization of the electron energy spectrum in the film
leads to a step-like dependence of differential conductance G(V) as a function of applied bias eV. The distance
between neighboring steps in eV equals the energy level spacing due to size quantization. We demonstrate that a
study of G(V) for both signs of the voltage maps the spectrum of energy levels above and below Fermi surface in
scanning tunneling experiments. |
