Abstract

A combined experimental and theoretical investigation of phononic properties in nanocrystal-based semiconductors reveals that unusually strong coupling between phonons and electrons originates from the mechanical softness of the surfaces of the nanocrystalline domains and sheds new light on their recombination in nanocrystal-based devices.
