Heterojunction Diode Leakage

quantumex04.in : Heterojunction Diode Leakage

Requires: Blaze/Quantum
Minimum Versions: Atlas 5.22.1.R

This example demonstrates the difference between an AlGaAs / GaAs heterojunction diode modeled with and without quantum physics.

In the first half of the file, the example calculates the forward and reverse characteristics of a classically modeled diode. In the second half of the example, the quantum model is switched on. Note that, as in the previous example, the qfactor is used to ramp the level of quantum moments included in the example for zero to unity.

The overlayed results show around an order of magnitude higher reverse leakage in the quantum case. This is due to the smearing of the electron concentration across the heterojunction.
