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…
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…
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…
Temporal evolution of low-temperature phonon sidebands in WSe monolayers
Roberto Rosati, Samuel Brem, Raül Perea-Causín +9
Low-temperature photoluminescence (PL) of hBN-encapsulated monolayer tungsten diselenide (WSe) shows a multitude of sharp emission peaks below the bright exciton. Some of them…
