Symmetry matters in graphene growth

Rice researchers find subtle interactions with substrate may lead to better control

(March 16, 2015) What lies beneath growing islands of graphene is important to its properties, according to a new study led by Rice University.
Scientists at Rice analyzed patterns of graphene – a single-atom-thick sheet of carbon – grown in a furnace via chemical vapor deposition. They discovered that the geometric relationship between graphene and the substrate, the underlying material on which carbon assembles atom by atom, determines how the island shapes emerge.
