Homogeneous Large-area Quasi-freestanding Monolayer and Bilayer Graphene on SiC
Davood Momeni Pakdehi, Klaus Pierz, Stefan Wundrack +9
In this study, we first show that the argon flow during epitaxial graphene growth is an important parameter to control the quality of the buffer and the graphene layer. Atomic forc…

Wafer scale growth and characterization of edge specific graphene nanoribbons
Alexei A. Zakharov, Nikolay A. Vinogradov, Johannes Aprojanz +5
One of the ways to use graphene in field effect transistors is to introduce a band gap by quantum confinement effect [1]. That is why narrow graphene nanoribbons (GNRs) with width…

Electron interference in ballistic graphene nanoconstrictions
Jens Baringhaus, Mikkel Settnes, Johannes Aprojanz +3
We have realized nanometer size constrictions in ballistic graphene nanoribbons grown on sidewalls of SiC mesa structures. The high quality of our devices allows the observation of…
