Interactions of electrons and Rydberg excitons in two-dimensional semiconductors
Arthur Christianen, Anna M. Seiler, Alperen TüÄen +1
Rydberg excitons in two-dimensional semiconductors provide sensitive and non-destructive probes of physics in proximal sample layers that host correlated electronic states. In part…
Optical Injection and Detection of Long-Lived Interlayer Excitons in van der Waals Heterostructures
Alperen TüÄen, Anna M. Seiler, Arthur Christianen +4
Interlayer excitons in semiconducting bilayers separated by insulating hBN layers constitute a promising platform for investigation of strongly correlated bosonic phases. Here, we…
The role of non-equilibrium populations in dark exciton formation
Paul Werner, Wiebke Bennecke, Jan Philipp Bange +15
In two-dimensional transition metal dichalcogenide structures, the optical excitation of a bright exciton may be followed by the formation of a plethora of lower energy dark states…
Hybrid Frenkel-Wannier excitons facilitate ultrafast energy transfer at a 2D-organic interface
Wiebke Bennecke, Ignacio Gonzalez Oliva, Jan Philipp Bange +13
Two-dimensional transition metal dichalcogenides (TMDs) and organic semiconductors (OSCs) have emerged as promising material platforms for next-generation optoelectronic devices. T…
Signatures of sliding Wigner crystals in bilayer graphene at zero and finite magnetic fields
Anna M. Seiler, Martin Statz, Christian Eckel +6
AB-stacked bilayer graphene has emerged as a fascinating yet simple platform for exploring macroscopic quantum phenomena of correlated electrons. Unexpectedly, a phase with negativ…
