Magnetic order induced polarization anomaly of Raman scattering in 2D magnet CrI
Yujun Zhang, Xiaohua Wu, BingBing Lv +16
The recent discovery of 2D magnets has revealed various intriguing phenomena due to the coupling between spin and other degree of freedoms (such as helical photoluminescence, nonre…
The Optical Properties and Plasmonics of Anisotropic 2-Dimensional Materials
Chong Wang, Guowei Zhang, Shenyang Huang +2
In the fast growing two-dimensional (2D) materials family, anisotropic 2D materials, with their intrinsic in-plane anisotropy, exhibit a great potential in optoelectronics. One suc…
Strain-tunable van der Waals interactions in few-layer black phosphorus
Shenyang Huang, Guowei Zhang, Fengren Fan +6
Interlayer interactions in 2D materials, also known as van der Waals (vdWs) interactions, play a critical role in the physical properties of layered materials. It is fascinating to…
Drastic enhancement of the Raman intensity in few-layer InSe by uniaxial strain
Chaoyu Song, Fengren Fan, Ningning Xuan +9
The vibrational and electronic properties of 2-dimensinal (2D) materials can be efficiently tuned by external strain due to their good stretchability. Resonant Raman spectroscopy i…
Electronic structures of air-exposed few-layer black phosphorus by optical spectroscopy
Fanjie Wang, Guowei Zhang, Shenyang Huang +5
The electronic structure of few-layer(FL) black phosphorus(BP) sensitively depends on the sample thickness, strain and doping. In this paper, we show that it is also vulnerable to…
Palladium Diselenide Long-Wavelength Infrared Photodetector with High Sensitivity and Stability
Mingsheng Long, Yang Wang, Peng Wang +11
A long-wavelength infrared (IR) photodetector based on two-dimensional materials working at room temperature would have wide applications in many aspects in remote sensing, thermal…
