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…
