| 摘 要： | 在GaP:N(Te)的光致发光谱(PL)上,第一次发现了Te~0束缚激子发光伴生的声子翼,其中参与的声子是Dean曾经提出的D声子。对实验结果尚未有肯定的解释。另外,对掺杂GaP PL谱上熟知的双伴线,提出了有助于澄清问题的见解。

| Abstract: | A kind of phonon wing phenomena related with neutral Te bound excitons in the photoluminescence
spectra of GaP: N(Te) is reported for the first time. The phonons involving in the
wing emissions seem to be the D-phonon observed by Dean Besides, opinions concerning the assignment
to the well known luminescence doublets in doped GaP are proposed, which might be
helpful to clear up some confusions in the problem. |
