Abstract :
Carriers among nonidentical multiple quantum wells (MQWs) will redistribute as temperature varies. This is due to strongly temperature-dependent Fermi-Dirac distribution, which favors carriers in high energy states in high temperature. As a result, the temperature characteristic of semiconductor can be improved.
