Ultrafast signatures of Dirac / flat-band hybrid states from time-resolved ARPES
Maria-Elisabeth Federl, Johannes Gradl, Franziska Bergmeier +12
Hybridization of highly itinerant Dirac electrons with localized flat-band states is predicted to yield emergent phenomena such as exotic heavy-fermion behaviour. Epitaxial graphen…
From stripes to hexagons: strain-induced 2D Pb phases confined between graphene and SiC
Markus Gruschwitz, Sergii Sologub, Chitran Ghosal +4
The intercalation of metals beneath graphene offers a powerful route to stabilizing and protecting novel two-dimensional (2D) phases. The epitaxial growth of Pb monolayers on SiC(0…
Si Intercalation Beneath Epitaxial Graphene: Modulating Mott States at the SiC(0001) Interface
Niclas Tilgner, Zamin Mamiyev, Susanne Wolff +4
Intercalation has proven to be a powerful tool for tailoring the electronic properties of freestanding graphene layers as well as for stabilizing the intercalated material in a two…
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…
