| Summary: | Using colloidal particles with different thermosensitivities, we observe the transition from a crystalline solid to a disordered glass by tuning the size mismatch of the constituent particles in quasi-two-dimensional configurations. The transition is clearly identifiable by the correlation functions of the orientational order parameters and its susceptibilities. Different from typical order-to-disorder transitions such as melting, where the underlying mechanism involves the diffusion of defects, the disordered phase in the crystal-to-glass transition grows via a nucleation process. The disordered clusters grow in size as the particle mismatch increases, and eventually percolate the whole system, which signifies the qualitative change from an ordered crystal to a disordered glass. |
