Vibrational dynamics of a two-dimensional microgranular crystal

Vibrational dynamics of a two-dimensional microgranular crystal

We study the dynamics of an ordered hexagonal monolayer of polystyrene microspheres adhered to a glass substrate coated with a thin aluminum layer. A laser-induced transient grating technique is employed to generate and detect three types of acoustic modes across the entire Brillouin zone in the Γ−K...
