Electric-field-tunable intervalley excitons and phonon replicas in bilayer WSe
Mashael M. Altaiary, Erfu Liu, Ching-Tarng Liang +7
We report the direct observation of intervalley exciton between the Q conduction valley and valence valley in bilayer WSe by photoluminescence. The Q exciton lies at ~18…

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…
