Projekat

Elektrohemijska sinteza i karakterizacija nanostrukturiranih funkcionalnih materijala za primenu u novim tehnologijama (MPNTR - 172046)

Sažetak

Morfologija elektrohemijski istaloženih dendrita srebra analizirana je tehnikom skenirajuće elektronske mikroskopije (SEM). Na osnovu morfoloških proučavanja predložena je struktura i mehanizam rasta dendrita. Dendrit srebra je dvojnikovani kristal sa {111} ravni dvojnikovanja i pravcima rasta <112>. Mehanizam rasta predstavlja kombinaciju tri procesa: a) rast ravni dvojnikovanja preko sistema uvučenih ivica, b) klizanje ravni dvojnikovanja i c) rast slojeva na završnim (111) pljosnima.
