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…
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…
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…
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…
The Shear Mode of Multi-Layer Graphene
P. H. Tan, W. P. Han, W. J. Zhao +9
We uncover the interlayer shear mode of multi-layer graphene samples, ranging from bilayer-graphene (BLG) to bulk graphite, and show that the corresponding Raman peak measures the…
