Valerius, Philipp, Herman, Alexander and Michely, Thomas (2019). Suppression of wrinkle formation in graphene on Ir(111) by high-temperature, low-energy ion irradiation. Nanotechnology, 30 (8). BRISTOL: IOP PUBLISHING LTD. ISSN 1361-6528
Full text not available from this repository.Abstract
Graphene on Ir(111) is irradiated with small fluences of 500 eV He ions at temperatures close to its chemical vapor deposition growth temperature. The ion irradiation experiments explore whether it is possible to suppress the formation of wrinkles in Gr during growth. It is found that the release of thermal mismatch strain by wrinkle formation can be entirely suppressed for an irradiation temperature of 880 degrees C. A model for the ion beam induced suppression of wrinkle formation in supported Gr is presented, and underpinned by experiments varying the irradiation temperature or involving intercalation subsequent to irradiation.
