Enhanced photoresponse in MoTe2 photodetectors with asymmetric graphene contacts
Xia Wei, Faguang Yan, Quanshan Lv +4
Atomically thin two dimensional (2D) materials are promising candidates for miniaturized high-performance optoelectronic devices. Here, we report on multilayer MoTe2 photodetectors…
Fast multicolor photodetectors based on graphene-contacted p-GaSe/n-InSe van der Waals heterostructures
Faguang Yan, Lixia Zhao, Amalia Patanè +10
The integration of different two-dimensional materials within a multilayer van der Waals (vdW) heterostructure offers a promising technology for realizing high performance opto-ele…
Photodetectors based on junctions of Two-Dimensional Transition metal dichalcogenides
Xia Wei, Faguang Yan, Chao Shen +2
Transition metal dichalcogenides (TMDCs) have gained considerable attention because of their novel properties and great potential applications. The flakes of TMDCs not only have gr…
Towards Fast Multicolor Photodetectors based on Graphene Contacted Vertical p-GaSe/n-InSe van der Waals Heterostructure
Faguang Yan, Dong Zhang, Wengang Luo +6
We investigated the electronic and optoelectronic properties of vertical van der Waals heterostructure photodetectors using layered p type GaSe and n type InSe, with graphene as th…
