FORMATION OF A PENTAGONAL PARTICLE STRUCTURE FROM COPPER NANOCLUSTERS

The structure o f pentagonal particles and the processes o f their formation from nanoclusters with the fifthorder symmetry axes are investigated by the methods o f computer modeling and scanning electron-ion microscopy using copper as an example. It is demonstrated that the mechanism o f cluster growth to pentagonal particles can be realized at which the volumetric stress present in noncrystal clusters will be released without breaking o f the fifth-order symmetry o f the growing cluster shape
