Differential transmission measurement of phonon bottleneck in self-assembled quantum dot intersubband relaxation

Abstract Time-resolved measurements of self-assembled In 0.4 Ga 0.6 As quantum dots indicate a phonon bottleneck between the electronic levels. The bottleneck becomes observable in a capture experiment, where fast relaxation processes are removed at low carrier densities and nongeminate capture of carriers is allowed. Carrier-density-dependent measurements confirm nongeminate capture. We perform a Monte Carlo simulation based on a random carrier capture model to explain the bottleneck signal.
