Evolution of high-temperature superconductivity from low-Tc phase tuned by carrier concentration in FeSe thin flakes
B. Lei, J. H. Cui, Z. J. Xiang +7
In contrast to bulk FeSe superconductor, heavily electron-doped FeSe-derived superconductors show relatively high Tc without hole Fermi surfaces and nodal superconducting gap struc…
Quantum Hall Effect in Black Phosphorus Two-dimensional Electron Gas
Likai Li, Fangyuan Yang, Guo Jun Ye +10
Development of new, high quality functional materials has been at the forefront of condensed matter research. The recent advent of two-dimensional black phosphorus has greatly enri…
Ultrafast pulse generation with black phosphorus
Diao Li, Henri Jussila, Lasse Karvonen +4
Black phosphorus has been recently rediscovered as a new and interesting two-dimensional material due to its unique electronic and optical properties. Here, we study the linear and…
Black Phosphorus Nanoelectromechanical Resonators Vibrating at Very High Frequencies
Zenghui Wang, Hao Jia, Xuqian Zheng +6
We report on experimental demonstration of a new type of nanoelectromechanical resonators based on black phosphorus crystals. Facilitated by a highly efficient dry transfer techniq…
Pressure-induced Lifshitz transition in black phosphorus
Z. J. Xiang, G. J. Ye, C. Shang +10
In a semimetal, both electron and hole carriers contribute to the density of states at the Fermi level. The small band overlaps and multi-band effects give rise to many novel elect…
