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…

Luminescence quenching via deep defect states: A recombination pathway via oxygen vacancies in Ce-doped YAG
Christopher Linderälv, Daniel Åberg, Paul Erhart
Luminescence quenching via non-radiative recombination channels limits the efficiency of optical materials such as phosphors and scintillators and therefore has implications for co…
