Graphene films grown over epitaxial metal films deposited on single-crystalline substrates give unique micropits with rectangular and triangular shapes, reflecting the crystallographic orientation of the substrate.
Technology
Inner Space
Metals encapsulated within carbon nanotubes by capillary action are prevented from crystallizing by the confined space of the nanotubes.
