| Research Abstract |
We have studied the dynamics of exciton hopping in an array of quantum dots to provide general insights on the transport and diffusion phenomena in a disordered and nonequilibrium system. Temperature dependent exciton hopping has been clarified by means of time-resolved and site-selective fluorescent measurements. We have provided analytical methods to extract several statistical quantities that characterize the dynamics of exciton hopping from the experimental data. Furthermore, for the microspectroscopic measurements, we implemented laser-diode based pump-probe microscopy and achieved sub-diffraction spatial resolution with picosecond time resolution.
