Enhanced nonlinear interaction of polaritons via excitonic Rydberg states in monolayer WSe2
Jie Gu, Valentin Walther, Lutz Waldecker +7
Strong optical nonlinearities play a central role in realizing quantum photonic technologies. In solid state systems, exciton-polaritons, which result from the hybridization of mat…
Rigid band shifts in two-dimensional semiconductors through environmental screening
Lutz Waldecker, Archana Raja, Malte Rösner +9
We investigate the effects of environmental dielectric screening on the electronic dispersion and the band gap in the atomically-thin, quasi two-dimensional (2D) semiconductor WS$_…
Intrinsic Lifetime of Higher Excitonic States in Tungsten Diselenide Monolayers
Samuel Brem, Jonas Zipfel, Malte Selig +7
The reduced dielectric screening in atomically thin transition metal dichalcogenides allows to study the hydrogen-like series of higher exciton states in optical spectra even at ro…
