| 英文摘要 | We report a direct observation of excitonic polaron in inas/gaas quantum dots using the photoluminescence (pl) spectroscopy. we observe that a new peak s' emerges below the s-shell which has anomalous temperature dependence emission energy. the peak s' anticrosses with s at a certain temperature, with a large anticrossing gap up to 31 mev. the behavior of the new peak, which cannot be interpreted using huang-rhys model, provides a direct evidence for strong coupling between exciton and lo phonons, and the formation of the excitonic polaron. the strong coupling between exciton and phonons opens a way to coherently control the polaron states. copyright (c) epla, 2010 |
