Quenching of Intervalley Exchange Coupling in the Presence of Momentum-Dark States in TMDCs
Malte Selig, Florian Katsch, Samuel Brem +3
Monolayers of transition metal dichalcogenides are promising materials for valleytronic applications, since they possess two individually addressable excitonic transitions at the n…
Ultrafast dynamics in monolayer TMDCs: the interplay of dark excitons, phonons and intervalley Coulomb exchange
Malte Selig, Florian Katsch, Robert Schmidt +4
Understanding the ultrafast coupling and relaxation mechanisms between valleys in transition metal dichalcogenide semiconductors is of crucial interest for future valleytronic devi…
Theory of exciton dynamics in time-resolved ARPES: intra- and intervalley scattering in two-dimensional semiconductors
Dominik Christiansen, Malte Selig, Ermin Malic +2
Time- and angle-resolved photoemission spectroscopy (trARPES) is a powerful spectroscopic method to measure the ultrafast electron dynamics directly in momentum-space. However, ban…
Intrinsic Lifetime of Higher Excitonic States in Tungsten Diselenide Monolayers
Samuel Brem, Jonas Zipfel, Malte Selig +7
The reduced dielectric screening in atomically thin transition metal dichalcogenides allows to study the hydrogen-like series of higher exciton states in optical spectra even at ro…
Phonon-assisted Photoluminescence from Dark Excitons in Monolayers of Transition Metal Dichalcogenides
Samuel Brem, August Ekman, Dominik Christiansen +7
The photoluminescence (PL) spectrum of transition metal dichalcogenides (TMDs) shows a multitude of emission peaks below the bright exciton line and not all of them have been expla…
Theory of optically induced Förster Coupling in van der Waals coupled Heterostuctures
Malte Selig, Ermin Malic, Kwang Jun Ahn +2
We investigate the impact of optically induced Förster coupling in van der Waals heterostructures consisting of graphene and a monolayer transition metal dichalcogenide (TMD). In p…
