Molecule signatures in photoluminescence spectra of transition metal dichalcogenides

Maja Feierabend, Gunnar Berghaeuser, Malte Selig +4

Monolayer transition metal dichalcogenides (TMDs) show an optimal surface-to-volume ratio and are thus promising candidates for novel molecule sensor devices. It was recently predi…

Dissecting spin-phonon equilibration in ferrimagnetic insulators by ultrafast lattice excitation

Sebastian F. Maehrlein, Ilie Radu, Pablo Maldonado +8

To gain control over magnetic order on ultrafast time scales, a fundamental understanding of the way electron spins interact with the surrounding crystal lattice is required. Howev…
