The geometry of the CISS effect
P. Hedegård, A. Kazimir, C. Lamers +3
Using scanning tunneling microscopy, and a careful selection of chiral molecules and anchoring groups, we systematically carried out a series of magnetoresistance experiments. We o…
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…
Confinement Epitaxy of Large-Area Two-Dimensional Sn at the Graphene/SiC Interface
Zamin Mamiyev, Niclas Tilgner, Narmina O. Balayeva +3
Confinement epitaxy beneath graphene stabilizes exotic material phases by restricting vertical growth and altering lateral diffusion, conditions unattainable on bare substrates. Ho…
Intercalant-induced Kekule ordering and gap opening in quasi-free-standing graphene
Huu Thoai Ngo, Zamin Mamiyev, Niklas Witt +2
We present a comprehensive investigation of the structural and electronic properties of Sn intercalated buffer layers on SiC(0001) using low-temperature scanning tunneling microsco…
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…
Mesoscopic scale study of lateral dynamics of Sn-intercalation of the buffer layer on SiC
Benno Harling, Zamin Mamiyev, Christoph Tegenkamp +1
The dynamics of Sn intercalation of the buffer layer on SiC was investigated with a frozen-in diffusion front using Kelvin Probe Force Microscopy. The technique allows to laterally…
Homogeneous doping of epitaxial graphene by Pb(111) islands: A magnetotransport study
Julian Koch, Sergii Sologub, Dorothee Sylvia Boesler +5
Proximity coupling is an effective approach for the functionalization of graphene. However, graphene's inertness inhibits the adsorption of closed films, thus favoring island growt…
Electronic correlations in epitaxial graphene: Mott states proximitized to a relativistic electron gas
Chitran Ghosal, Siheon Ryee, Zamin Mamiyev +3
Graphene, renowned for its exceptional electronic and optical properties as a robust 2D material, traditionally lacks electronic correlation effects. Proximity coupling offers a pr…
