Deposition of nanosized amino acid functionalized bismuth oxido clusters on gold surfaces
Annika Morgenstern, Rico Thomas, Apoorva Sharma +9
Bismuth compounds are of growing interest with regard to potential applications in catalysis, medicine and electronics, for which their environmentally benign nature is one of the…
Silicon carbide stacking-order-induced doping variation in epitaxial graphene
Davood Momeni Pakdehi, Philip Schädlich, T. T. Nhung Nguyen +7
Generally, it is supposed that the Fermi level in epitaxial graphene is controlled by two effects: p-type polarization doping induced by the bulk of the hexagonal SiC(0001) substra…
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…
Comeback of epitaxial graphene for electronics: large-area growth of bilayer-free graphene on SiC
Mattias Kruskopf, Davood Momeni Pakdehi, Klaus Pierz +12
We present a new fabrication method for epitaxial graphene on SiC which enables the growth of ultra-smooth defect- and bilayer-free graphene sheets with an unprecedented reproducib…
Direct growth of low-doped graphene on Ge/Si(001) surfaces
J. Dabrowski, G. Lippert, J. Avila +12
The practical difficulties to use graphene in microelectronics and optoelectronics is that the available methods to grow graphene are not easily integrated in the mainstream techno…
Direct Measurement of Surface Transport on a Bulk Topological Insulator
Lucas Barreto, Lisa Kühnemund, Frederik Edler +7
Topological insulators are guaranteed to support metallic surface states on an insulating bulk, and one should thus expect that the electronic transport in these materials is domin…
