Cavity-enhanced circular dichroism in a van der Waals antiferromagnet
Shu-Liang Ren, Simin Pang, Shan Guan +9
Broken symmetry plays a pivotal role in determining the macroscopic electrical, optical, magnetic, and topological properties of materials. Circular dichroism (CD) has been widely…
s-d coupling enhanced phonon anharmonicity in copper-based compounds
Kaike Yang, Huai Yang, Yujia Sun +7
Materials with ultralow thermal conductivity are of great interest for efficient energy conversion and thermal barrier coating. Copper-based semiconductors such as copper chalcogen…
Breakdown of Raman Selection Rules By Fröhlich Interaction in Few-Layer WS
Qing-Hai Tan, Kai-Xuan Xu, Yu-Jia Sun +5
The Raman selection rules arise from the crystal symmetry and then determine the Raman activity and polarization of scattered phonon modes. However, these selection rules can be br…
Observation of forbidden phonons and dark excitons by resonance Raman scattering in few-layer WS
Qing-Hai Tan, Yu-Jia Sun, Xue-Lu Liu +4
The optical properties of the two-dimensional (2D) crystals are dominated by tightly bound electron-hole pairs (excitons) and lattice vibration modes (phonons). The exciton-phonon…
