Colloidal crystals for 0.7 μm PMMA/PHSA spheres were fabricated using temperature gradient control and density matching. It was found that the structure of the resulting crystals is rchp. A new dynamic light scattering technique was used to account for the single particle and lattice dynamics of hard sphere crystals just on the solid side of melting. These entrophic crystals were found to exhibit short wavelength phonons with a similar dispersion to conventional materials.
