Orange slicing

An orange can be cut into eight eighths that can be re-assembled to represent the 1/8 fractional volume contribution from the atom at each corner of a primitive cubic unit cell. (Companion Demonstration 3.1)

fcc lattice to cell

Generation of an FCC unit cell from an FCC extended structure. (Companion Demonstration 3.2)

fcc unit cell

Corner and face-shared atoms in an FCC unit cell. (Companion Demonstration 3.2)

fcc unit cell to lattice

Generation of an FCC extended structure from an FCC unit cell. (Companion Demonstration 3.2)

Solid solutions

Substitutional solid solutions with a constant total composition of A + Z and random placement of these atoms at the sites at which they occur in the structure. Blue diamonds represent atom A, and yellow squares represent atom Z. (Companion Figure 3.14)
