Hot-carrier transfer across a nanoparticle-molecule junction: The importance of orbital hybridization and level alignment
Jakub Fojt, Tuomas P Rossi, Paul Erhart
While direct hot-carrier transfer can increase photo-catalytic activity, it is difficult to discern experimentally and competes with several other mechanisms. To shed light on thes…
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.…
Dipolar coupling of nanoparticle-molecule assemblies: An efficient approach for studying strong coupling
Jakub Fojt, Tuomas P. Rossi, Tomasz J. Antosiewicz +2
Strong light-matter interactions facilitate not only emerging applications in quantum and non-linear optics but also modifications of materials properties. In particular the latter…
Tunable Phases of Moiré Excitons in van der Waals Heterostructures
Samuel Brem, Christopher Linderälv, Paul Erhart +1
Stacking monolayers of transition metal dichalcogenides into a heterostructure with a finite twist-angle gives rise to artificial moiré superlattices with a tunable periodicity. As…
Hot-Carrier Generation in Plasmonic Nanoparticles: The Importance of Atomic Structure
Tuomas P. Rossi, Paul Erhart, Mikael Kuisma
Metal nanoparticles are attractive for plasmon-enhanced generation of hot carriers, which may be harnessed in photochemical reactions. In this work, we analyze the coherent femtose…
Strong plasmon-molecule coupling at the nanoscale revealed by first-principles modeling
Tuomas P. Rossi, Timur Shegai, Paul Erhart +1
Strong light-matter interactions in both the single-emitter and collective strong coupling regimes attract significant attention due to emerging quantum and nonlinear optics applic…
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…
Interlayer exciton dynamics in van der Waals heterostructures
Simon Ovesen, Samuel Brem, Christopher Linderälv +4
Exciton binding energies of hundreds of meV and strong light absorption in the optical frequency range make transition metal dichalcogenides (TMDs) promising for novel optoelectron…
Resistivity Anomaly in Weyl Semimetal candidate Molybdenum Telluride
Dhavala Suri, Christopher Linderalv, Bogdan Karpiak +8
The Weyl semi-metal candidate MoTe is expected to exhibit a range of exotic electronic transport properties. It exhibits a structural phase transition near room temperature t…
