GaN晶体薄膜的光致发光谱均存在一个非常宽且比较复杂的黄光发射带,从给出的谱线形状可判断,其包含有多个发光峰,这说明黄光发光带是由多个跃迁过程产生的。Pankove和Hutchby小组系统地研究了35种元素注入GaN薄膜后的低温 (78K)光致发光行为, 并发现金属元素的注入均存在较强的特征光发射;其余的元素在2.15eV附近有一较宽的发射峰,如C,Li,Be,Al和Si均存在较强的发射带,这些发射带被认为是同注入带来的缺陷有关。
其中,聚芴类蓝光二极管的光谱稳定性及低能发射带(LEEB)的起源问题是国际上近十年的热点问题之一.本文系统概述了低能发射带的现象、表征方法以及可能的形成机理,包括链间作用导致的激基...
