我们用高分辨光谱研究了超纯金刚石中间接激子的精细结构分裂。的质量各向异性分裂的作用已被揭示通过比较与减少矩阵元素的电子和空穴的声子散射的辐射复合的群论计算。除了交换和自旋-轨道相互作用外，还考虑了质量各向异性分裂，成功地再现了所观察到的精细结构态的能级和耦合强度。
We have investigated fine structure splitting of indirect excitons in ultrapure diamond by high-resolution spectroscopy. The role of the mass-anisotropy splitting has been revealed by comparison with group-theoretical calculations of the reduced matrix elements for phonon scattering of electrons and holes followed by the radiative recombination. The observed energy levels and coupling strengths of the fine structure states are successfully reproduced by inclusion of the mass-anisotropy splitting in addition to the exchange and spin-orbit interactions.
