Binary Colloidal Glass Structure near a Wall
Abstract
We have used video microscopy and digital imaging to study a mixture of uniform, highly charged 0.6 μm/0.3 μm diameter polystyrene as a function of sphere volume fraction at a ratio of big to small spheres ranging from zero to one. At lower volume fractions we observed an AB5 structure, at higher volume fractions we have observed substitutionally disordered FCC. We present studies of the translational and bond-orientational order parameters for the crystalline and glass structures observed.
