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 MoTe2, 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.

单层 MoTe2 中带电激子的谷赝自旋弛豫

由磁场引起的塞曼效应在单层半导体过渡金属二硫化物的布里渊区的 K + 和 K - 点处引入了两个谷之间的分裂。因此，光致发光信号表现出与场相关的圆偏振度。我们在单层 MoTe2 中的 trion 的情况下对这种效应进行了全面研究，表明尽管时间积分数据允许我们推断出 trion 状态的 g 因子，但这种分析无法通过时间显示的时间尺度来证实- 解决实验。
