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…
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 int…
