Spin-split band hybridization in graphene proximitized with -RuCl nanosheets
Soudabeh Mashhadi, Youngwook Kim, Jeongwoo Kim +8
Proximity effects induced in the 2D Dirac material graphene potentially open access to novel and intriguing physical phenomena. Thus far, the coupling between graphene and ferromag…
Reliable postprocessing improvement of van der Waals heterostructures
Youngwook Kim, Patrick Herlinger, Takashi Taniguchi +2
The successful assembly of heterostructures consisting of several layers of different 2D materials in arbitrary order by exploiting van der Waals forces has truly been a game chang…
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…
Charged defects in graphene and the ionicity of hexagonal boron nitride in direct images
Jannik C. Meyer, Simon Kurasch, Hye Jin Park +10
We report on the detection and charge distribution analysis for nitrogen substitutional dopants in single layer graphene membranes by aberration-corrected high-resolution transmiss…
Electronic decoupling of an epitaxial graphene monolayer by gold intercalation
Isabella Gierz, Takayuki Suzuki, Dong Su Lee +7
The application of graphene in electronic devices requires large scale epitaxial growth. The presence of the substrate, however, usually reduces the charge carrier mobility conside…
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…
