Analytical and Numerical Solution of the Double Barrier Problem
28 Jun 2010  Teaching Materials  Contributor(s): Gerhard Klimeck, Parijat Sengupta, Dragica Vasileska
Tunneling is fully quantummechanical effect that does not have classical analog. Tunneling has revolutionized surface science by its utilization in scanning tunneling microscopes. In some device applications tunneling is required for the operation of the device (Resonant tunneling diodes, EEPROMs – floating gate memories), but in some cases it leads to unwanted power dissipation, such as gate leakage in both MOS and Schottky transistors. Resonant tunneling diodes, due to the tunneling …
