Formation of moiré interlayer excitons in space and time
David Schmitt, Jan Philipp Bange, Wiebke Bennecke +11
Moiré superlattices in atomically thin van-der-Waals heterostructures hold great promise for an extended control of electronic and valleytronic lifetimes, the confinement of excito…
Terahertz fingerprint of monolayer Wigner crystals
Samuel Brem, Ermin Malic
The strong Coulomb interaction in monolayer semiconductors represents a unique opportunity for the realization of Wigner crystals without external magnetic fields. In this work, we…
Valley-exchange coupling probed by angle-resolved photoluminescence
Joshua J. P Thompson, Samuel Brem, Hanlin Fang +7
The optical properties of monolayer transition metal dichalcogenides are dominated by tightly-bound excitons. They form at distinct valleys in reciprocal space, and can interact vi…
Interlayer exciton landscape in WS/tetracene heterostructures
Joshua J. P. Thompson, Victoria Lumsargis, Maja Feierabend +5
The vertical stacking of two-dimensional materials into heterostructures gives rise to a plethora of intriguing optoelectronic properties and presents an unprecedented potential fo…
Exciton landscape in van der Waals heterostructures
Joakim Hagel, Samuel Brem, Christopher Linderälv +2
van der Waals heterostructures consisting of vertically stacked transition-metal dichalcogenides (TMDs) exhibit a rich landscape of bright and dark intra- and interlayer excitons.…
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…
