Simulation of quantum dot devices by coupling of quantum master equations and semi-classical transport theory

摘要

We discuss a comprehensive modeling approach for the simulation of quantum dot devices based on the coupling of the van Roosbroeck system with a Markovian quantum master equation. The model equations describe the flow of electrons and holes in semiconductor devices along with a quantum kinetic many-body approach for the quantum dot physics. The consistency of the model equations with respect to non-equilibrium thermodynamics is investigated. We present numerical simulations of an electrically driven single-photon source based on a single quantum dot.
