Exciton-driven change of phonon modes causes strong temperature dependent bandgap shift in nanoclusters
The fundamental bandgap E(g) of a semiconductor—often determined by means of optical spectroscopy—represents its characteristic fingerprint and changes distinctively with temperature. Here, we demonstrate that in magic sized II-VI clusters containing only 26 atoms, a pronounced weakening of the bond...
