| 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.; 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.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-07-18t13:30:42z no. of bitstreams: 0; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-07-18t13:30:42z no. of bitstreams: 0; we thanks prof. y.j. yan and x. q. li for helpful discussions. this work was supported by national fundamental research program, the innovation funds from the chinese academy of sciences, national natural science foundation of china (grant nos. 60621064, 10874162, 10734060).; 国内 |
