Coherent Dynamics of Charge Carriers in γ-InSe Revealed by Ultrafast Spectroscopy
Jianwei Shen, Jiayu Liang, Qixu Zhao +8
For highly efficient ultrathin solar cells, layered indium selenide (InSe), a van der Waals solid, has shown a great promise. In this paper, we study the coherent dynamics of charg…
