Biexcitons are bound in CsPbBr3 Perovskite Nanocrystals
Yoonjae Park, David T. Limmer
We study the energetics of quasi-particle excitations in CsPbBr3 perovskite nanocrystals using path integral molecular dynamics simulations. Employing detailed molecular models, we…

Size-dependent lattice symmetry breaking determines the exciton fine structure of perovskite nanocrystals
Daniel Weinberg, Yoonjae Park, David T. Limmer +1
The ordering of optically bright and dark excitonic states in lead-halide perovskite nanocrystals has been a matter of some debate. It has been proposed that the unusually short ra…
