Schematic drawing of the development of Au lamellar nanocondensates:a bulk nucleation from Au clusters denoted asdark polyhedra,b coarsening via capillarity effect,c Brownian motion/rotation of imperfectly attached domains,d epitaxial nucleation of Ih/Dh (denoted as largered polyhedra) from lamellar domains,e explosive nucleation of lamellar fragments due to heterogeneous catalysis by well developed {111} of Ih/Dh.f Lamellae with 5- and 6-coordinated atoms within the layer and van der waals’ attraction between the layers roll up upon electron irradiation
