Figure 1
Schematic illustrating the various families of shapes accessible to f.c.c. materials. The initial reduction and nucleation forms a seed that is either single crystalline, singly twinned, multiply twinned or planar with multiple parallel staking faults (which often fall under the umbrella of `singly twinned'). Green, purple and orange represent {100}, {110} and {111} surfaces, and the parameter R is the ratio between the growth velocity of {100} and {111} facets. Adapted from Xia et al. (2009BB83).
