Raman Scattering at Pure Graphene Zigzag Edges
Benjamin Krauss, Péter Nemes-Incze, Viera Skakalova +3
Theory has predicted rich and very distinct physics for graphene devices with boundaries that follow either the armchair or zigzag crystallographic directions. A prerequisite to di…
Band structure engineering of epitaxial graphene on SiC by molecular doping
Camilla Coletti, Christian Riedl, Dong Su Lee +5
Epitaxial graphene on SiC(0001) suffers from strong intrinsic n-type doping. We demonstrate that the excess negative charge can be fully compensated by non-covalently functionalizi…
Raman spectra of epitaxial graphene on SiC and of epitaxial graphene transferred to SiO2
Dong Su Lee, Christian Riedl, Benjamin Krauß +3
Raman spectra were measured for mono-, bi- and trilayer graphene grown on SiC by solid state graphitization, whereby the number of layers was pre-assigned by angle-resolved ultravi…
