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…
Direct measurement of key exciton properties: energy, dynamics and spatial distribution of the wave function
Shuo Dong, Michele Puppin, Tommaso Pincelli +15
Excitons, Coulomb-bound electron-hole pairs, are the fundamental excitations governing the optoelectronic properties of semiconductors. While optical signatures of excitons have be…
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…
Microscopic picture of electron-phonon interaction in two-dimensional halide perovskites
David Feldstein, Raul Perea-Causin, Shuli Wang +5
Perovskites have attracted much attention due to their remarkable optical properties. While it is well established that excitons dominate their optical response, the impact of high…
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…
