Interlayer breathing and shear modes in NbSe2 atomic layers
Rui He, Jeremiah van Baren, Jia-An Yan +6
Atomically thin NbSe2 is a metallic layered transition metal dichalcogenide (TMD) with considerably different crystallographic structure and electronic properties from other TMDs,…
Observation of interlayer phonon modes in van der Waals heterostructures
Chun Hung Lui, Zhipeng Ye, Chao Ji +9
We have investigated the vibrational properties of van der Waals heterostructures of monolayer transition metal dichalcogenides (TMDs), specifically MoS2/WSe2 and MoSe2/MoS2 hetero…
Stacking-dependent shear modes in trilayer graphene
Chun Hung Lui, Zhipeng Ye, Courtney Keiser +2
We observed distinct interlayer shear mode Raman spectra for trilayer graphene with ABA and ABC stacking order. There are two rigid-plane shear-mode phonon branches in trilayer gra…
Temperature-activated layer-breathing vibrations in few-layer graphene
Chun Hung Lui, Zhipeng Ye, Courtney Keiser +2
We investigated the low-frequency Raman spectra of freestanding few-layer graphene (FLG) at varying temperatures (400 - 900 K) controlled by laser heating. At high temperature, we…
