Microscopic understanding of ultrafast charge transfer in van-der-Waals heterostructures
R. Krause, S. Aeschlimann, M. Chavez-Cervantes +7
Van-der-Waals heterostructures show many intriguing phenomena including ultrafast charge separation following strong excitonic absorption in the visible spectral range. However, de…
Momentum-resolved observation of exciton formation dynamics in monolayer WS
Robert Wallauer, Raul Perea-Causin, Lasse Münster +8
The dynamics of exciton formation in transition metal dichalcogenides is difficult to measure experimentally, since many momentum-indirect exciton states are not accessible to opti…
Phonon-assisted Exciton Dissociation in Transition Metal Dichalcogenides
Raul Perea-Causin, Samuel Brem, Ermin Malic
Monolayers of transition metal dichalcogenides (TMDs) have been established in the last years as promising materials for novel optoelectronic devices. However, the performance of s…
Criteria for deterministic single-photon emission in two-dimensional atomic crystals
Joshua J. P. Thompson, Samuel Brem, Hanlin Fang +4
The deterministic production of single-photons from two dimensional materials promises to usher in a new generation of photonic quantum devices. In this work, we outline criteria b…
Strain-dependent exciton diffusion in transition metal dichalcogenides
Roberto Rosati, Samuel Brem, Raül Perea-Causín +5
Monolayers of transition metal dichalcogenides (TMDs) have a remarkable excitonic landscape with deeply bound bright and dark exciton states. Their properties are strongly affected…
Tunable Phases of Moiré Excitons in van der Waals Heterostructures
Samuel Brem, Christopher Linderälv, Paul Erhart +1
Stacking monolayers of transition metal dichalcogenides into a heterostructure with a finite twist-angle gives rise to artificial moiré superlattices with a tunable periodicity. As…
