Experimental observation of coupled valley and spin Hall effect in p-doped WSe2 devices
Terry Y. T. Hung, Avinash Rustagi, Shengjiao Zhang +2
Giant spin Hall effect (GSHE) has been observed in heavy metal materials such as Ta, Pt, and W, where spins are polarized in the surface plane and perpendicular to the charge curre…
Direct Observation of Valley Coupled Topological Current in MoS
Terry Y. T. Hung, Kerem Y. Camsari, Shengjiao Zhang +2
The valley degree of freedom of electrons in two-dimensional transition metal dichalcogenides has been extensively studied by theory, optical and optoelectronic experiments. Howeve…
Two-Dimensional h-BN and MoS2 as Diffusion Barriers for Ultra-Scaled Copper Interconnects
Chun-Li Lo, Massimo Catalano, Kirby K. H. Smithe +5
Copper interconnects in modern integrated circuits require ultra-thin barriers to prevent intermixing of Cu with surrounding dielectric materials. Conventional barriers rely on met…
Monolayer MoS2/GaAs heterostructure self-driven photodetector with extremely high detectivity
Zhijuan Xu, Shisheng Lin, Xiaoqiang Li +5
Two dimensional material/semiconductor heterostructures offer alternative platforms for optoelectronic devices other than conventional Schottky and p-n junction devices. Herein, we…
Opening the band gap of graphene through silicon doping for improved performance of graphene/GaAs heterojunction solar cells
Shengjiao Zhang, Shisheng Lin, Xiaoqiang Li +7
Graphene has attracted increasing interests due to its remarkable properties, however, the zero band gap of monolayer graphene might limit its further electronic and optoelectronic…
Semiconductor quantum dots enhanced graphene/CdTe heterostructure solar cells by photo-induced doping
Xiaoqiang Li, Shengjiao Zhang, Peng Wang +4
We report a type of solar cells based on graphene/CdTe Schottky heterostructure, which can be improved by surface engineering as graphene is one-atomic thin. By coating a layer of…
High performance solar cells based on graphene-GaAs heterostructures
Xiaoqiang Li, Shengjiao Zhang, Peng Wang +5
The honeycomb connection of carbon atoms by covalent bonds in a macroscopic two-dimensional scale leads to fascinating graphene and solar cell based on graphene/silicon Schottky di…
