Coexistence of rhcp and fcc phases in hard-sphere colloidal crystals

Abstract:

We present results for high-resolution small-angle single-crystal X-ray diffraction of hard-sphere silica colloidal crystals. Our results indicate that the stacking probability a of finding an fee stacking sequence in a strongly compressed sample can only have two discrete values of either 0.5 (for rhcp) or 1 (for fcc) in contrast to previous observations on more dilute systems that metastable hard-sphere rhcp crystals may have various values of α. This suggests that, in a concentrated sample...
