Exciton optics, dynamics and transport in atomically thin semiconductors
Raul Perea-Causin, Daniel Erkensten, Jamie M. Fitzgerald +4
Atomically thin semiconductors such as transition metal dichalcogenide (TMD) monolayers exhibit a very strong Coulomb interaction, giving rise to a rich exciton landscape. This mak…
Phonon-assisted inter-valley scattering determines ultrafast exciton dynamics in MoSe bilayers
Sophia Helmrich, Kevin Sampson, Di Huang +10
While valleys (energy extrema) are present in all band structures of solids, their preeminent role in determining exciton resonances and dynamics in atomically thin transition meta…
Singlet exciton optics and phonon-mediated dynamics in oligoacene semiconductor crystals
Joshua J. P. Thompson, Dominik Muth, Sebastian Anhäuser +4
Organic semiconductor crystals stand out as an efficient, cheap and diverse platform for realising optoelectronic applications. The optical response of these crystals is governed b…
Ultrafast phonon-driven charge transfer in van der Waals heterostructures
Giuseppe Meneghini, Samuel Brem, Ermin Malic
Van der Waals heterostructures built by vertically stacked transition metal dichalcogenides (TMDs) exhibit a rich energy landscape including interlayer and intervalley excitons. Re…
Exciton transport in a moiré potential: from hopping to dispersive regime
Willy Knorr, Samuel Brem, Giuseppe Meneghini +1
The propagation of excitons in TMD monolayers has been intensively studied revealing interesting many-particle effects, such as halo formation and non-classical diffusion. Initial…
Nonclassical Exciton Diffusion in Monolayer WSe2
Koloman Wagner, Jonas Zipfel, Roberto Rosati +9
We experimentally demonstrate time-resolved exciton propagation in a monolayer semiconductor at cryogenic temperatures. Monitoring phonon-assisted recombination of dark states, we…
