Valley polarization in MoS2 monolayers by optical pumping
Hualing Zeng, Junfeng Dai, Wang Yao +2
We report experimental evidences on selective occupation of the degenerate valleys in MoS2 monolayers by circularly polarized optical pumping. Over 30% valley polarization has been…

Magneto-electric photocurrent generated by direct inter-band transitions in InGaAs/InAlAs two-dimensional electron gas
Junfeng Dai, Hai-Zhou Lu, C. L. Yang +3
We report observation of magneto-electric photocurrent generated via direct inter-band transitions in an InGaAs/InAlAs two-dimensional electron gas excited by a linearly polarized…
