In electrochemical reaction: Electrocrystallization
Mechanisms associated with screw dislocations, or twinning edges, can provide for a continuous growth of crystals. The screw dislocation mechanism, shown in Figure 3B, is made possible by a specific fault often found in the crystal lattice that may be called a dislocation originating from a shift of…

work of Frank

In Sir Charles Frank
…1949 that spiral features called screw dislocations would provide a place for crystal growth to happen that could explain the observed rates. In a startling coincidence, at that same conference shortly after Frank’s presentation, mineralogist L.J. Griffin (who had been working independently of Frank) confirmed Frank’s theory by presenting the…
