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…
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…
