Luminescent emission of excited Rydberg excitons from monolayer WSe2
Shao-Yu Chen, Zhengguang Lu, Thomas Goldstein +11
We report the experimental observation of radiative recombination from Rydberg excitons in a two-dimensional semiconductor, monolayer WSe2, encapsulated in hexagonal boron nitride.…
Asymmetric Two-Terminal Graphene Detector for Broadband Radiofrequency Heterodyne- and Self-Mixing
Jiayue Tong, Matthew C. Conte, Thomas Goldstein +3
Graphene, a single atomic layer of covalently bonded carbon atoms, has been investigated intensively for optoelectronics and represents a promising candidate for high-speed electro…
Superior valley polarization and coherence of 2s excitons in monolayer WSe2
Shao-Yu Chen, Thomas Goldstein, Jiayue Tong +3
We report experimental observation of 2s exciton radiative emission from monolayer tungsten diselenide, enabled by hexagonal boron nitride protected high-quality samples. The 2s lu…
Raman scattering and anomalous Stokes anti-Stokes ratio in MoTe2 atomic layers
Thomas Goldstein, Shao-Yu Chen, Di Xiao +2
Stokes and anti-Stokes Raman scattering are performed on atomic layers of hexagonal molybdenum ditelluride (MoTe2), a prototypical transition metal dichalcogenide (TMDC) semiconduc…
Antenna enhanced graphene THz emitter and detector
Jiayue Tong, Martin Muthee, Shao-Yu Chen +2
Recent intense electrical and optical studies of graphene have pushed the material to the forefront of optoelectronic research. Of particular interest is the few terahertz (THz) fr…
