抄録 | The many-body effect of the excitons in the semiconductor quantum dots is investigated in the frequency and time regions. The Rabi oscillation of the exciton in the semiconductor quantum dots is observed by the stimulated photon echo method. This is the first direct observation of the Rabi oscillation of the excitons. The signal intensity changes periodically with the excitation intensity. The sharp spectrum from the single quantum dot is also observed by the micro-photoluminescence. The existence of phonon bottleneck is clarified from the temporal shape of the photoluminescence signal. These results show that the quantum dots is one of the good candidates for the device of the quantum computation. |
