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…
Hot Phonons in an Electrically Biased Graphene Constriction
Dong-Hun Chae, Benjamin Krauss, Klaus von Klitzing +1
Phonon carrier interactions can have significant impact on device performance. They can be probed by measuring the phonon lifetime, which reflects the interaction strength of a pho…
