Exciton States in Quantum Dot Solids: Excitation Transfer and Dynamic Decorrelation
Published

Abstract
Coherent exciton transport in Quantum dot solids is determined by electron and hole interdot tunneling and dipole-dipole interdot excitation transfer. We present a tight-binding theory of coupled dots to understand the interdot coupling and hybridization of states in dot solids. Results show that significant coupling is possible. Exiciton dynamics in a dot solid is simulated by use of a Hubbard model that includes interdot carrier tunneling, electron-hole attraction and Forster exciton excitation transfer. Dynamic exciton decorrelation is driven by carrier tunneling. Dynamic exciton dephasing is driven by excitation transfer.
