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…
Interlayer breathing and shear modes in NbSe2 atomic layers
Rui He, Jeremiah van Baren, Jia-An Yan +6
Atomically thin NbSe2 is a metallic layered transition metal dichalcogenide (TMD) with considerably different crystallographic structure and electronic properties from other TMDs,…
