| 英文摘要 | Photoluminescence measurements have been performed on cubic gan films with carrier concentration as low as 3 x 10(13) cm(-3). from the temperature and excitation intensity dependence, the emission lines at 3.268, 3.150 and 3.081 ev were assigned to the excitonic, donor-acceptor pair, and free-to-acceptor transitions, respectively additionally, we observed two additional emission lines at 2.926 and 2.821 ev, and suggested that they belong to donor-acceptor pair transitions. furthermore, from the temperature dependence of integral intensities, we confirmed that three donor-acceptor pair transitions (3.150, 2.926, and 2.821 ev) are from a common shallow donor to three different accepters. the excitonic emission at 3.216 ev has a full-width-at-half-maximum value of 41 mev at room temperature, which indicates a good optical quality of our sample. |
