Lithographically-controlled liquid metal diffusion in graphene: Fabrication and magneto-transport signatures of superconductivity
S. Wundrack, M. Bothe, M. Jaime +15
Metal intercalation in epitaxial graphene enables the emergence of proximity-induced superconductivity and modified quantum transport properties. However, systematic transport stud…
Growth dynamics of graphene buffer layer formation on ultra-smooth SiC(0001) surfaces
Julia Guse, Stefan Wundrack, Marius Eckert +14
In this study the growth process of epitaxial graphene on SiC was investigated systematically. The transition from the initial buffer layer growth to the formation of the first mon…
Liquid metal intercalation of epitaxial graphene: large-area gallenene layer fabrication through gallium self-propagation at ambient conditions
S. Wundrack, D. Momeni Pakdehi, W. Dempwolf +8
We demonstrate the fabrication of an ultra thin gallium film, also known as gallenene, beneath epitaxial graphene on 6H-SiC under ambient conditions triggered by liquid gallium int…
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…
Tailoring the SiC surface - a morphology study on the epitaxial growth of graphene and its buffer layer
Mattias Kruskopf, Klaus Pierz, Davood Momeni Pakdehi +4
We investigate the growth of the graphene buffer layer and the involved step bunching behavior of the silicon carbide substrate surface using atomic force microscopy. The formation…
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…
