Abstract
Med moderne epitaksiale vækstteknikker som molecular beam epitaxy og sputtering kan man frembringe krystallinske lag, der er roteret i forhold til underlaget – såkaldt epitaksial rotation. Artiklen introducerer både klassisk teori, som Novaco og McTagues elastiske model, og ny forståelse baseret på endelig-størrelse-effekter. Ved at analysere interaktionen mellem små krystaller og deres substrat viser forfatterne, hvordan moiré-mønstre og deres symmetri bestemmer stabile rotationsvinkler. En fascinerende kobling mellem geometri, energi og materialefysik, der giver nyt lys over selvorganisering i nanoskala-systemer.
