论文摘要
磁场引起的Zeeman效应引入了两个山谷的k $^+$和k $^ - 单层半导体过渡金属二进制二进制二进制中的两个山谷之间的分裂。因此，光致发光信号表现出圆极化的磁场依赖性程度。在单层MOTE $ _2 $的情况下，我们对这种效果进行了全面研究，表明，尽管时间综合数据使我们能够推断出Trion态的G因子，但在时间分辨实验中揭示的时间表无法证实这种分析。
Zeeman effect induced by the magnetic field introduces a splitting between the two valleys at K$^+$ and K$^-$ points of the Brillouin zone in monolayer semiconducting transition metal dichalcogenides. In consequence, the photoluminescence signal exhibits a field dependent degree of circular polarization. We present a comprehensive study of this effect in the case of a trion in monolayer MoTe$_2$, showing that although time integrated data allows us to deduce a g-factor of the trion state, such an analysis cannot be substantiated by the timescales revealed in the time-resolved experiments.
