Glass Transitions in Quasi-Two-Dimensional Suspensions of Colloidal Ellipsoids
Glass Transitions in Quasi-Two-Dimensional Suspensions of Colloidal Ellipsoids
We observed a two-step glass transition in monolayers of colloidal ellipsoids by video microscopy. The glass transition in the rotational degree of freedom was at a lower density than that in the translational degree of freedom. Between the two transitions, ellipsoids formed an orientational glass. Approaching the respective glass transitions, …
