Dispersive diffusion of electronic energy in an impurity band

Klaus Godzik, Joshua Jortner

Research output: Contribution to journalArticlepeer-review


We applied the continuous time random walk model for the study of electronic energ transfer (EET) in an impurity band of a mixed molecular crystal, providing explicit results for the time-dependent diffusion coefficient D(t) in a system where the EET is dominated by dipole-dipole interactions. For short times D(t) ∝ t- 1 6, while for long times an ordinary diffusive process prevails.
