Contact-to-connectivity crossover in the vibrational dynamics of nanoparticle assemblies.
Classical contact mechanics is widely used to describe mechanical coupling in nanoparticle assemblies, yet its validity at the nanoscale remains experimentally unresolved. Here, we investigate size-dependent collective vibrational dynamics in self-assembled polystyrene nanoparticle films with particle diameters from 20...
