Layer-dependent interlayer antiferromagnetic spin reorientation in air-stable semiconductor CrSBr
Chen Ye, Cong Wang, Qiong Wu +11
Magnetic van der Waals (vdW) materials offer a fantastic platform to investigate and exploit rich spin configurations stabilized in reduced dimensions. One tantalizing magnetic ord…
Enhanced Valley Zeeman Splitting in Fe-Doped Monolayer MoS2
Qi Li, Xiaoxu Zhao, Longjiang Deng +15
The Zeeman effect offers unique opportunities for magnetic manipulation of the spin degree of freedom (DOF). Recently, valley Zeeman splitting, referring to the lifting of valley d…
Layer engineered interlayer excitons
Qinghai Tan, Abdullah Rasmita, Si Li +6
Photoluminescence (PL) from excitons serves as a powerful tool to characterize the optoelectronic property and band structure of semiconductors, especially for atomically thin 2D t…
Room Temperature Polariton Lasing in All-Inorganic Perovskites
Rui Su, Carole Diederichs, Jun Wang +6
Polariton lasing is the coherent emission arising from a macroscopic polariton condensate first proposed in 1996. Over the past two decades, polariton lasing has been demonstrated…
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…
Large Frequency Change with Thickness in Interlayer Breathing Mode - Significant Interlayer Interactions in Few Layer Black Phosphorus
Xin Luo, Xin Lu, Gavin Kok Wai Koon +4
Bulk black phosphorus (BP) consists of puckered layers of phosphorus atoms. Few-layer BP, obtained from bulk BP by exfoliation, is an emerging candidate as a channel material in po…
Stacking sequence determines Raman intensities of observed interlayer shear modes in 2D layered materials - A general bond polarizability model
Xin Luo, Chunxiao Cong, Xin Lu +3
2D layered materials have recently attracted tremendous interest due to their fascinating properties and potential applications. The interlayer interactions are much weaker than th…
Effects of Lower Symmetry and Dimensionality on Raman Spectra in 2D WSe2
Xin Luo, Yanyuan Zhao, Jun Zhang +4
We report the observation and interpretation of new Raman peaks in few-layer tungsten diselenide (WSe2), induced by the reduction of symmetry going from 3D to 2D. In general, Raman…
Rapid and reliable thickness identification of two-dimensional nanosheets using optical microscopy
Hai Li, Jumiati Wu, Xiao Huang +5
The physical and electronic properties of ultrathin two-dimensional (2D) layered nanomaterials are highly related to their thickness. Therefore, the rapid and accurate identificati…
Anomalous Frequency Trends in MoS2 Thin Films Attributed to Surface Effects

Interlayer breathing and shear modes in few-trilayer MoS2 and WSe2
Yanyuan Zhao, Xin Luo, Hai Li +8
Two-dimensional (2D) layered transition metal dichalcogenides (TMDs) have recently attracted tremendous interest as potential valleytronic and nano-electronic materials, in additio…
Direct Observation of Inner and Outer G' Band Double-resonance Raman Scattering in Free Standing Graphene
Zhiqiang Luo, Chunxiao Cong, Jun Zhang +2
In contrary to the widely reported single and symmetric peak feature of G' (or 2D) band in Raman spectrum of graphene, we herein report the observation of splitting in G' band in f…
