Ultrahigh-mobility semiconducting epitaxial graphene on silicon carbide (preprint PDF)

The joke goes that graphene can do everything but leave the lab... Roughly speaking, graphene gets its wide bangap from underlying material which has it even wider. The semiconducting graphene thus always needs bulk layer of wide bandgap material, i.e. silicone carbide beneath it. Given the fact how multilayered the present integrated circuits are there is still big chalenge in how this monolayer sandwich can be translated into a compact still functional multilayers.
