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…
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…
Impact of Electrical Contacts on Transition Metal Dichalcogenides-Based Acoustoelectric and Acousto-Photoelectric Devices
Benjamin Mayer, Felix M. Ehring, Clemens Strobl +4
We study the impact of electrical contact barriers in hybrid WSe-LiNbO-based acoustoelectric and acousto-photoelectric devices using a combination of scanning photocurrent…
Collective neutral excitations as sensitive probe for the quality of 2D charge carrier systems in ultra-pure GaAs quantum wells
Ursula Wurstbauer, Michael J. Manfra, Ken W. West +1
Ultra-clean low-dimensional interacting charge carrier systems are the basis to explore correlated states and phases. We report the observation of very narrow collective intersubba…
