| Abstract : |
A theoretical study of current density for
the case of tunneling through phenomenological
{1} and variationally {2} calculated
metal-vacuum-metal (MVM) potential barriers
is presented. The two-dimensional time dependent
Schrödinger equation is solved numerically.
Spectroscopic effects (e.g. the effects of
low work function tip patches) as well as
electron focusing effects are investigated
within the framework of this model.
Predictions of semiclassical calculations
(e.g. geometrical asymmetries in I(V) curves)
are verified.
This work was partially supported by the
Swiss National Science Foundation.
