| 7. | The isoelectronic system of gap : n has been investigated extensively in the dilute limit since 1965 . thomas et al identified that a series of sharp emission lines in gap : n were due to the recombinations of excitons bound to either isolated nitrogen centers or various nitrogen pair centers
这些谱线来自于等电子杂质n形成的束缚激子态(孤立n中心和nn _ i对)辐射复合产生的零声子线及其声子伴线。 |
| 8. | This indicated an absence of deep trapping centers . this peak was still observed at room temperature , temperature . the presence of this intrinsic near - band - gap emission line in the pl spectrum even at room temperature is a further indication for the high quality of the epitaxial layer
Znse薄膜样品在77k时，光致发光谱中只观测到了近带边的发射，而且这一发光一直持续到室温，说明在si衬底上lp - mocvd外延生长的znse薄膜具有较高的质量。 |
