Selectively controlled ferromagnets by electric fields in van der Waals ferromagnetic heterojunctions
Zi-Ao Wang, Weishan Xue, Faguang Yan +7
Charge transfer plays a key role at the interfaces of heterostructures, which can affect electronic structures and ultimately the physical properties of the materials. However, cha…
Exciton valley dynamics in monolayer WSe2 probed by the two-color ultrafast Kerr rotation
Tengfei Yan, Xiaofen Qiao, Pingheng Tan +1
The newly developed two-dimensional layered materials provide perfect platform for valley-spintronics exploration. To determine the prospect of utilizing the valley degree of freed…
Anomalous valley polarization in monolayer MoSe2
Anmin Zhang, Jiahe Fan, Yusheng Li +8
Modern electronic devices heavily rely on the accurate control of charge and spin of electrons. The emergence of controllable valley degree of freedom brings new possibilities and…
Valley depolarization in monolayer WSe2
Tengfei Yan, Xiaofen Qiao, Pingheng Tan +1
We have systematically examined the circular polarization of monolayer WSe2 at different temperature, excitation energy and exciton density. The valley depolarization in WSe2 is ex…
Collective magnetization dynamics in ferromagnetic (Ga,Mn)As mediated by photo-excited carriers
Hang Li, Xinyu Liu, Ying-Yuan Zhou +2
We present a study of photo-excited magnetization dynamics in ferromagnetic (Ga,Mn)As films observed by time-resolved magneto-optical measurements. The magnetization precession tri…
Gate Tuning of High-Performance InSe-Based Photodetectors Using Graphene Electrodes
Wengang Luo, Yufei Cao, Pingan Hu +6
In order to increase the response speed of the InSe-based photodetector with high photoresponsivity, graphene is used as the transparent electrodes to modify the difference of the…
Strong enhancement of photoresponsivity with shrinking the electrodes spacing in few layer GaSe photodetectors
Yufei Cao, Kaiming Cai, Pingan Hu +6
A critical challenge for the integration of the optoelectronics is that photodetectors have relatively poor sensitivities at the nanometer scale. It is generally believed that a la…
Temperature and Electron Density Dependence of Spin Relaxation in GaAs/AlGaAs Quantum Well
L. F. Han, Y. G. Zhu, X. H. Zhang +3
Temperature and carrier density dependent spin dynamics for GaAs/AlGaAs quantum wells (QWs) with different structural symmetry has been studied by using time-resolved Kerr rotation…
