Resonant Raman signatures of bright and momentum-dark exciton coupled by intervalley phonon scattering in monolayer WSe2
Hendrik Lambers, Nihit Saigal, Lara Blinov +3
Exciton-phonon coupling in atomically thin transition metal dichalcogenides governs key processes such as exciton thermalization and intervalley scattering and remains challenging…
Collective charge excitations between moiré-minibands in twisted WSe2 bilayers from resonant inelastic light scattering
Nihit Saigal, Lennart Klebl, Hendrik Lambers +5
We establish low-temperature resonant inelastic light scattering (RILS) spectroscopy as a tool to probe the formation of a series of moiré-bands in twisted WSe_{2} bilayers by acce…
Exciton manifolds in highly ambipolar doped WS2
David Otto Tiede, Nihit Saigal, Hossein Ostovar +3
The disentanglement of single and many particle properties in 2D semiconductors and their dependencies on high carrier concentration is challenging to experimentally study by pure…
Spectroscopic imaging ellipsometry of two-dimensional TMDC heterostructures
Florian Sigger, Hendrik Lambers, Nisi Katharina +4
Semiconducting two-dimensional materials and their heterostructures gained a lot of interest for applications as well as fundamental studies due to their rich optical properties. A…
