Kristalografski defekt
Kristalografski defekt je prekid pravilnih obrazaca rasporeda atoma ili molekula u kristalnim čvrstim materijama. Položaji i orijentacije čestica, koje se ponavljaju na fiksnim rastojanjima određenim parametrima jedinične ćelije u kristalima, pokazuju periodičnu kristalnu strukturu, ali ona je obično nesavršena.[2][3][4][5] Često se karakteriše nekoliko tipova defekata: tačkasti defekti, linijski defekti, planarni defekti, defekti mase. Topološka homotopija uspostavlja matematički metod karakterizacije.
