摘要

据报道，$\pmb{Ge}_{1-x}\pmb{Sn}_{x}$合金中的光自旋取向揭示了IV族材料是自旋光电器件的有前途的候选材料。在这里，我们指出磁光研究可以用来确定自旋和载流子寿命，而不使用时间分辨装置。

Magneto-optical investigation of the dynamics of spin-polarized carriers in GeSn heterostructures

Optical spin orientation has been reported in $\pmb{Ge}_{1-x}\pmb{Sn}_{x}$ alloys unveiling group IV materials as promising candidates for spin-optoelectronic devices. Here we point out that magneto-optical investigations can be leveraged to determine the spin and carrier lifetime without utilizing a time-resolved apparatus.
