Polytypism and Unexpected Strong Interlayer Coupling of two-Dimensional Layered ReS2
Xiao-Fen Qiao, Jiang-Bin Wu, Lin-Wei Zhou +7
The anisotropic two-dimensional (2D) van der Waals (vdW) layered materials, with both scientific interest and potential application, have one more dimension to tune the properties…
Substrate-free layer-number identification of two-dimensional materials: A case of MoWS alloy
Xiao-Fen Qiao, Xiao-Li Li, Xin Zhang +4
Any of two or more two-dimensional (2D) materials with similar properties can be alloyed into a new layered material, namely, 2D alloy. Individual monolayer in 2D alloys are kept t…
Interface coupling in twisted multilayer graphene by resonant Raman spectroscopy of layer breathing modes
Jiang-Bin Wu, Zhi-Xin Hu, Xin Zhang +9
Raman spectroscopy is the prime non-destructive characterization tool for graphene and related layered materials. The shear (C) and layer breathing modes (LBMs) are due to relative…
Phonon and Raman scattering of two-dimensional transition metal dichalcogenides from monolayer, multilayer to bulk material
Xin Zhang, Xiao-Fen Qiao, Wei Shi +3
Two-dimensional (2D) transition metal dichalcogenide (TMD) nanosheets exhibit remarkable electronic and optical properties. The 2D features, sizable bandgaps, and recent advances i…
