| 抄録: | We have studied the dynamics of highly dense exciton and electron-hole (e-h) systems in GaN by means of optical Kerr-gate time-resolved photoluminescence (PL) spectral measurements. In high-density e-h pairs above the Mott density, the broad electron-hole plasma emission appears at first, and then the narrow PL due to the biexciton and the inelastic exciton-exciton scattering is observed. When the pump light resonantly excites the A excitons, highly dense e-h systems with low effective temperatures are formed, and unique PL bands are observed. These PL peaks can be explained by a picture that the A excitons are scattered into the A, B , and C bands. |
