Master Equations for the Micro-States Description of Carrier Relaxation and Recombination in Quantum Dots
Abstract
Modeling of time resolved experiments on zero-dimensional quantum dots requires a conceptually different approach than for higher dimensional semiconductors. A description via master equations for the micro-states is necessary since quantum dots behave as independent objects. The impact of finite inter-level relaxation time is included in our model. Description via conventional rate equations for population probabilities averaged over the dot ensemble is inadequate. Two different time resolved luminescence experiments for quantum dot systems with fast and slow inter-level relaxation, respectively, are modeled to provide typical applications of our approach.
