Quantum beats of exciton-polarons in CsPbI3 perovskite nanocrystals
A. V. Trifonov, M. O. Nestoklon, M. -A. Hollberg +10
Exciton-phonon interactions govern the energy level spectrum and thus the optical response in semiconductors. In this respect, lead-halide perovskite nanocrystals represent a uniqu…

Francesco Monticone, N. Asger Mortensen, Antonio I. Fernández-Domínguez +63
Photonic technologies continue to drive the quest for new optical materials with unprecedented responses. A major frontier in this field is the exploration of nonlocal (spatially d…

The interaction between exciton and acoustic phonons via deformation potential in PbS nanocrystals is calculated in the model. The size-dependence of the Hu…
Optical transitions, exciton radiative decay, and valley coherence in lead chalcogenide quantum dots
S. V. Goupalov, E. L. Ivchenko, M. O. Nestoklon
We propose the concept of valley coherence and superradiance in the reciprocal space and show that it leads to an -fold decrease of the bright exciton radiative lifetime in quan…
