From Anomalous to Normal: Temperature Dependence of the Band Gap in Two-Dimensional Black Phosphorus
Shenyang Huang, Fanjie Wang, Guowei Zhang +11
The temperature dependence of the band gap is crucial to a semiconductor. Bulk black phosphorus (BP) is known to exhibit an anomalous behavior. Through optical spectroscopy, here w…
The optical conductivity of few-layer black phosphorus by infrared spectroscopy
Guowei Zhang, Shenyang Huang, Fanjie Wang +6
The strength of light-matter interaction is of central importance in photonics and optoelectronics. For many widely studied two-dimensional semiconductors, such as MoS2, the optica…
Nodal and nematic superconducting phases in NbSe2 monolayers from competing superconducting channels
Chang-woo Cho, Jian Lyu, Liheng An +10
Transition metal dichalcogenides like 2H-NbSe2 in their two-dimensional (2D) form exhibit Ising superconductivity with the quasiparticle spins are firmly pinned in the direction pe…
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…
Raman evidence for dimerization and Mott collapse in -RuCl under pressures
Gaomin Li, Xiaobin Chen, Yuan Gan +16
We perform Raman spectroscopy studies on -RuCl at room temperature to explore its phase transitions of magnetism and chemical bonding under pressures. The Raman measurements…
