Modeling Direct Band-to-Band Tunneling using QTBM

Lidija Filipovic, Oskar Baumgartner, Hans Kosina
This work focuses on modeling the tunneling mechanism in direct semiconductors. An effective barrier is extracted between the valence and conduction band, by defining the barrier as valence-like near the valence band and conduction band-like near the conduction band. The transition occurs at a point obtained by momentum matching. Computation of transition coefficient is performed using the quantum transmitting boundary method.
