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…
Identifying Contact Barrier Types in Few-Layer MoS2 Devices Using Correlative IV, LBIC, and Bias-Dependent KPFM
Ariane Ufer, Zeinab Eftekhari, Benjamin Mayer +4
Electrical contacts between metals and two-dimensional (2D) semiconductors such as molybdenum disulfide (MoS2) critically govern device performance, yet their microscopic nature re…
High-Energy Interlayer Exciton Ensembles in MoSe/WSe Heterostructures by Laguerre-Gaussian Excitation
Mirco Troue, Johannes Figueiredo, Gabriel Mittermair +7
We reveal the higher energetic luminescence part of interlayer exciton ensembles in MoSe/WSe heterostructures upon excitation by an optical Laguerre-Gaussian mode. The exci…
Precise Twist Angle Determination in twisted WSe2 via Optical Moiré Phonons
Nicolai-Leonid Bathen, Thorsten Deilmann, Ana Senkić +7
Twisted bilayers of transition metal dichalcogenides (TMDC) form moiré superlattices resulting in moiré minibands in momentum space and hosting localized excitons in real space. Wh…
Laterally Extended States of Interlayer Excitons in Reconstructed MoSe/WSe Heterostructures
Johannes Figueiredo, Marten Richter, Mirco Troue +8
Heterostructures made from 2D transition-metal dichalcogenides are known as ideal platforms to explore excitonic phenomena ranging from correlated moiré excitons to degenerate inte…
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…
