Current fabrication routes, which rely on metal substrates, require post synthesis transfer of the graphene onto a Si wafer or in the case of epitaxial growth on SiC, temperatures above 1000 {\\deg}C are required. Both the handling difficulty and high temperatures are not best suited to present day silicon technology. We report a facile chemical vapor deposition approach in which nano-graphene and few layer graphene is directly formed over magnesium oxide and can be achieved at temperatures as low as 32","authors_text":"Alicja Bachmatiuk, Andrew Scott, Bernd B\\\"uchner, Felix B\\\"orrnert, Gianaurelio Cuniberti, Jamie H.
