Scanning Electron Microscope Pictures of AB Binary Crystals With The CsCl Structure.

university crest



For a size ratio of 0.736 I found a binary with a AB CsCl structure. This configuration is made up of interlocking cubes of the two species such that at the centre of each cube of species 1 there is a particle of species 2.

The images below were taken from samples containing particles with radii 367.7nm and 270.6nm and are believed to be the first showing binary hard-sphere crystals with this arrangement.
