Control of Raman scattering quantum interference pathways in graphene
Xue Chen, Sven Reichardt, Miao-Ling Lin +8
Graphene is an ideal platform to study the coherence of quantum interference pathways by tuning doping or laser excitation energy. The latter produces a Raman excitation profile th…
Determining layer number of two dimensional flakes of transition-metal dichalcogenides by the Raman intensity from substrate
Xiao-Li Li, Xiao-Fen Qiao, Wen-Peng Han +4
Transition-metal dichalcogenide (TMD) semiconductors have been widely studied due to their distinctive electronic and optical properties. The property of TMD flakes is a function o…
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…
Raman spectroscopy at the edges of multilayer graphene
Q. -Q. Li, X. Zhang, W. -P. Han +4
Edges naturally exist in a single-layer graphene sample. Similarly, individual graphene layers in a multilayer graphene sample contribute their own edges. We study the Raman spectr…
The Interlayer Shear Modes in Twisted Multi-layer Graphenes: Interlayer coupling, Davydov Splitting and Intensity Resonance
Jiang-Bin Wu, Xin Zhang, Mari Ijas +6
Graphene and other two-dimensional crystals can be combined to form various hybrids and heterostructures, creating materials on demand, in which the interlayer coupling at the inte…
The ultra-low-frequency shear modes of 2-4 layer graphenes observed in their scroll structures at edges
Ping-Heng Tan, Jiang-Bin Wu, Wen-Peng Han +4
The in-plane shear modes between neighbor-layers of 2-4 layer graphenes (LGs) and the corresponding graphene scrolls rolled up by 2-4LGs were investigated by Raman scattering. In c…
Lattice dynamics in mono- and few-layer sheets of WS2 and WSe2
Weijie Zhao, Zohreh Ghorannevis, Amara Kiran Kumar +6
Thickness is one of the fundamental parameters that define the electronic, optical, and thermal properties of two-dimensional (2D) crystals. Phonons in molybdenum disulfide (MoS2)…
Shear and Layer Breathing Modes in Multilayer MoS2
X. Zhang, W. P. Han, J. B. Wu +5
We study by Raman scattering the shear and layer breathing modes in multilayer MoS2. These are identified by polarization measurements and symmetry analysis. Their positions change…
