Magneto-photoluminescence of exciton Rydberg states in monolayer WSe
Erfu Liu, Jeremiah van Baren, Takashi Taniguchi +3
Monolayer WSe hosts a series of exciton Rydberg states denoted by the principal quantum number n = 1, 2, 3, etc. While most research focuses on their absorption properties, the…
Gate tunable dark trions in monolayer WSe
Erfu Liu, Jeremiah van Baren, Zhengguang Lu +5
We report the observation and gate manipulation of intrinsic dark trions in monolayer WSe. By using ultraclean WSe devices encapsulated by boron nitride, we directly resolv…
Cleavage Tendency of Anisotropic Two Dimensional Materials: ReX2 (X=S, Se) and WTe2
Haifeng Wang, Erfu Liu, Yu Wang +4
With unique distorted 1T structure and the associated in-plane anisotropic properties, mono- and few-layer ReX2 (X=S, Se) have recently attracted particular interest. Based on expe…
Intrinsic p-type W-based transition metal dichalcogenide by substitutional Ta-doping
Yajun Fu, Mingsheng Long, Anyuan Gao +10
Two-dimensional (2D) transition metal dichalcogenides (TMDs) have recently emerged as promising candidates for future electronics and optoelectronics. While most of TMDs are intrin…
Room-temperature high detectivity mid-infrared photodetectors based on black arsenic phosphorus
Mingsheng Long, Anyuan Gao, Peng Wang +12
The mid-infrared (MIR) spectral range, pertaining to important applications such as molecular 'fingerprint' imaging, remote sensing, free space telecommunication and optical radar,…
