摘要：

A simple model of field induced evaporation/desorption from a negatively biased surface is proposed. The desorption of a surface atom takes place through a cascade of electron tunneling from the substrate to the atom and that from the atom to the outer vacuum. The desorption rate is estimated for a Si surface by an analysis of the dynamical behaviour of the atom over the diabatic potential surfaces taking into account the local temperature raise of the desorption site.
