1D resonant quantum tunneling

Per Sundqvist, ABB Corporate Research AB

The model sets up boundary conditions for the Schrödinger equation
in order to achive tunneling solutions. A resonant barrier potential is created with 1nm separation-width and 0.2nm oxide thickness barriers of 4eV. The result is plotted as the transmission coefficient t^2 vs. the energy (parametric solver). The resosnances are close to to the quantized levels for a particle in a box.

It is better to provide 1-2 page report on this work so that before downloading one can read it. Also it will help to understand the capability of the software to them who did not buy the software and thinking for demo etc.
