Dome-shaped carbon nanoislands on Ir(111)
We studied the first stages of graphene growth on Ir(111) with high-resolution XPS combined with DFT calculations. We demonstrate that the geodesic-like carbon nanoislands which form at low C coverage interact with the substrate only at the periphery.

By combining high-resolution photoelectron spectroscopy and ab initio calculations, we show that carbon nanoislands formed during the growth of a long-range ordered graphene layer on Ir(111) assume a peculiar domelike shape and are bound to the substrate only at the periphery. |
