Identification and Structural Characterization of Twisted Atomically Thin Bilayer Materials by Deep Learning
Haitao Yang, Ruiqi Hu, Heng Wu +11
Two-dimensional materials are expected to play an important role in next-generation electronics and optoelectronic devices. Recently, twisted bilayer graphene and transition metal…
Plasmonic nanocavity-enabled universal detection of layer-breathing vibrations in two-dimensional materials
Wu Heng, Lin Miao-Ling, Yan Sen +12
Conventional Raman spectroscopy faces inherent limitations in detecting interlayer layer breathing (LB) vibrations with inherently weak electron-phonon coupling or Raman inactivity…
Anomalous Gate-tunable Capacitance in Van der Waals Heterostructures
Linshang Chen, Haoran Long, Heng Wu +10
The ferroelectricity emerging in non-polar graphene/hexagonal boron nitride (hBN) heterostructures has drawn considerable attention because of its fascinating properties and promis…
Raman Forbidden Layer-Breathing Modes in Layered Semiconductor Materials Activated by Phonon and Optical Cavity Effects
Miao-Ling Lin, Jiang-Bin Wu, Xue-Lu Liu +9
We report Raman forbidden layer-breathing modes (LBMs) in layered semiconductor materials (LSMs). The intensity distribution of all observed LBMs depends on layer number, incident…
