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…
Graphene-capped bismuthene on SiC as a platform for correlated quantum spin Hall edge states
Huu Thoai Ngo, Zamin Mamiyev, Niclas Tilgner +4
Epitaxial bismuthene on SiC(0001) hosts symmetry-protected metallic edge states within a large bulk band gap, establishing it as a promising two-dimensional topological insulator f…
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…
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…
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…
Plasmon Standing Waves by Oxidation of Si(553)-Au
Z. Mamiyev, M. Tzschoppe, C. Huck +2
Self-assembled Au atomic wires on stepped Si surfaces are metallic, as evidenced by a one-dimensionally dispersing plasmonic excitation. Here we investigate the effects of oxidizat…
