Graphene floats on SiC !

Epitaxial graphene grown on SiC has excellent quality in terms of mobility and is a candidate for microelectronics industry. However, graphene's interaction with SiC disturbs most of the properties. In a recent ACS Nano report, researchers have used oxygen as an intercalant to lift graphene from SiC and opens up ways for  further applications.
