Exciton-driven change of phonon modes causes strong temperature dependent bandgap shift in nanoclusters
The bandgap of nanostructures usually follows the bulk value upon temperature change. Here, the authors find that in small nanocrystals a weakening of the bonds due to optical excitation causes a pronounced phonon shift, leading to a drastic enhancement of the bandgap’s temperature dependence.
