Emission spectrum of quasi-resonant laterally coupled quantum dots
arXiv:1107.1590 · doi:10.1103/PhysRevB.84.235312
Abstract
We calculate the emission spectrum of neutral and charged excitons in a pair of laterally coupled InGaAs quantum dots with nearly degenerate energy levels. As the interdot distance decreases, a number of changes take place in the emission spectrum which can be used as indications of molecular coupling. These signatures ensue from the stronger tunnel-coupling of trions as compared to that of neutral excitons.
