本文报道了在6H-SiC衬底上生长的GaN中深铁受主的塞曼行为的光学研究。在1.2988 eV的近红外发光跃迁的特征基态分裂使得先前基于ODMR结果提出的对Fe~(3+)的明确归属。观测到的8ms的发光寿命和激发态的精细结构与4T1(G)-6Al(S)的跃迁相一致。发现4T1(G)态只与e型声子模弱耦合。
We report an optical investigation of the Zeeman behavior of the deep iron acceptor in GaN grown on 6H–SiC. The characteristic ground state splitting of the near‐infrared luminescence transition at 1.2988 eV allows for an unambiguous assignment to Fe3+previously proposed on the basis of ODMR results. The observed luminescence lifetime of 8 ms as well as the fine structure of the excited state are consistent with a 4T1(G)–6A1(S) transition. The 4T1(G) state is found to couple only weakly to e‐type phonon modes.
