Carrier dynamics in graphene: ultrafast many-particle phenomena
Ermin Malic, Torben Winzer, Florian Wendler +10
Graphene is an ideal material to study fundamental Coulomb- and phonon-induced carrier scattering processes. Its remarkable gapless and linear band structure opens up new carrier r…
Dielectric Engineering of Electronic Correlations in a van der Waals Heterostructure
Philipp Steinleitner, Philipp Merkl, Alexander Graf +10
Heterostructures of van der Waals bonded layered materials offer unique means to tailor dielectric screening with atomic-layer precision, opening a fertile field of fundamental res…
Dark-exciton based strain sensing in transition metal dichalcogenides
Maja Feierabend, Zahra Khatibi, Gunnar Berghäuser +1
The trend towards ever smaller high-performance devices in modern technology requires novel materials with new functionalities. The recent emergence of atomically thin two-dimensio…
Impact of strain on the excitonic linewidth in transition metal dichalcogenides
Zahra Khatibi, Maja Feierabend, Malte Selig +4
Monolayer transition metal dichalcogenides (TMDs) are known to be highly sensitive to externally applied tensile or compressive strain. In particular, strain can be exploited as a…
Anomalous optical saturation of low-energy Dirac states in graphene and its implication for nonlinear optics
Behrooz Semnani, Roland Jago, Safieddin Safavi-Naeini +3
We reveal that optical saturation of the low-energy states takes place in graphene for arbitrarily weak electromagnetic fields. This effect originates from the diverging field-indu…
Slow noncollinear Coulomb scattering in the vicinity of the Dirac point in graphene
J. C. König-Otto, M. Mittendorff, T. Winzer +9
The Coulomb scattering dynamics in graphene in energetic proximity to the Dirac point is investigated by polarization resolved pump-probe spectroscopy and microscopic theory. Colli…
