Birefringence-Driven Anisotropic -MoO3 Optical Cavities
Jia-Liang Xie, Ting-Ting Wang, Chen-Kai Liu +4
Many anisotropic layered materials, despite their strong in-plane birefringence, exhibit substantial visible absorption, which severely restricts cavity lengths and hinders the obs…
Quantitatively predicting angle-resolved polarized Raman intensity of anisotropic layered materials
Jia-Liang Xie, Tao Liu, Yu-Chen Leng +8
Angle-resolved polarized Raman (ARPR) spectroscopy provides insights into optical anisotropy and symmetry-related electron-photon/electron-phonon couplings of anisotropic layered m…
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…
