Observation of Transient Trion Induced by Ultrafast Charge Transfer in Graphene/MoS2 Heterostructure

Autor: Wang, Chen, Chen, Yu, Ma, Qiushi, Suo, Peng, Sun, Kaiwen, Cheng, Yifan, Lin, Xian, Liu, Weimin, Ma, Guohong

Van der Waals (Vdw) heterostructures constructed from TMDCs provide an ideal platform for exploring various quasiparticle behaviors, with trion-composed of neutral exciton and charged carrier-being a notable example. There are typically three methods

Temporal-Spatial Manipulation of Bi-Focal Bi-Chromatic Fields for Terahertz Radiations

Autor: Zhao, Jingjing, Zhang, Yizhu, Gao, Yanjun, Li, Meng, Liu, Xiaokun, Liu, Weimin, Yan, Tian-Min, Jiang, Yuhai

Mixing the fundamental ($\omega$) and the second harmonic (2$\omega$) waves in gas phase is a widely employed technique for emitting terahertz (THz) pulses. The THz generation driven by bi-chromatic fields can be described by the photocurrent model,

Spectroscopic Evidence for Interfacial Charge Separation and Recombination in Graphene-MoS2 Vertical Heterostructures

Autor: Zou, Yuqing, Zhang, Zeyu, Wang, Chunwei, Cheng, Yifan, Wang, Chen, Sun, Kaiwen, Zhang, Wenjie, Suo, Peng, Lin, Xian, Ma, Hong, Leng, Yuxin, Liu, Weimin, Du, Juan, Ma, Guohong

Vertical van der Waals (vdW) heterostructures consisting of graphene (Gr) and transition metal dichalcogenides (TMDs) have created a fascinating platform for exploring optical and electronic properties in the two-dimensional limit. Previous study has
