Electron transmission through a potential barrier in the presence of an electromagnetic field: unitary transformation method
Abstract
The unitary transformation method is applied to the problem of the transmission through a one-dimensional rectangular barrier of an electron that is simultaneously acted upon by a laser beam. The latter is represented by a clasical plane electromagnetic wave in the dipole approximation. It is shown that the transmission probability increases exponentially with increasing field strength. The application of the results to the case of a metal-oxide-semiconductor junction is discussed.
