NEGF Formulism Question
I’m not too familiar with the NEGF formalism. But had a very basic question.
I’ve read that NEGF can be viewed as a “Quantum Boltzmann Equation”. When taking moments of the classical boltzmann equation and making some assumptions/approximations we arrive at an expression for the current density in the semiconductor. Namely that J = Jdrift + Jdiff, which is the backbone of commercial TCAD.
I’m wondering if a similar action is performed on the so called “Quantum Boltzmann Equation”, can get a form of the following: J = Jdrift + Jdiff + Jqm, where Jqm includes effects such as band-to-band tunneling??
Sorry for the elementary question but I’m rather new to NEGF concept.
