Observation of Fano resonance in photoluminescence of a two-dimensional magnetic semiconductor
Pingfan Gu, Qinghai Tan, Yi Wan +10
Quantum interference gives rise to the asymmetric Fano resonance line shape when the final states of an electronic transition follows within a continuum of states and a discrete st…
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…
Physical origin of Davydov splitting and resonant Raman spectroscopy of Davydov components in multilayer MoTe2
Q. J. Song, Q. H. Tan, X. Zhang +6
We systematically study the high-resolution and polarized Raman spectra of multilayer (ML) MoTe2. The layer-breathing (LB) and shear (C) modes are observed in the ultralow-frequenc…
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…
