Emergence of a non-bulk hexagonal FeS single layer via phase transformation
Affan Safeer, Wejdan Beida, Felix Oberbauer +8
Two-dimensional materials can stabilize crystal structures that are absent from their bulk counterparts, offering opportunities for materials design. Here, we report the synthesis…
Substrate Role in Polaron Formation on Single-layer Transition Metal Dihalides
Affan Safeer, Oktay Güleryüz, Guangyao Miao +3
Single-layer transition metal dihalides grown on conducting substrates were shown to host stable polarons. Here, we investigate polarons in insulating single-layer MnBr grown b…
MnBr on the graphene on Ir(110) substrate: growth, structure, and super-moirè
Affan Safeer, Oktay Güleryüz, Nicolae Atodiresei +3
Single-layer MnBr is grown on graphene (Gr) supported by Ir(110) and investigated using low-energy electron diffraction, scanning tunneling microscopy, and spectroscopy. The st…
Which chromium-sulfur compounds exist as 2D material?
Affan Safeer, Mahdi Ghorbani-Asl, Wouter Jolie +3
Two-dimensional (2D) chromium-sulfides are synthesized by molecular beam epitaxy using graphene as a substrate. Structure characterization by employing scanning tunneling microscop…
Atomic-scale Dzyaloshinskii-Moriya-modified Yoshimori spirals in Fe double layer on Ir(110)
Timo Knispel, Vasily Tseplyaev, Gustav Bihlmayer +3
Ultrathin magnetic films on heavy metal substrates with strong spin-orbit coupling provide versatile platforms for exploring novel spin textures. So far, structurally open fcc(110)…
Engineering two-dimensional materials from single-layer NbS
Timo Knispel, Daniela Mohrenstecher, Carsten Speckmann +10
Starting from a single layer of NbS grown on graphene by molecular beam epitaxy, the single unit cell thick 2D materials NbS-2D and NbS-2D are created using…
Tip-induced creation and Jahn-Teller distortions of sulfur vacancies in single-layer MoS
Daniel Jansen, Tfyeche Tounsi, Jeison Fischer +4
We present an atomically precise technique to create sulfur vacancies and control their atomic configurations in single-layer MoS. It involves adsorbed Fe atoms and the tip o…
Growth of aligned and twisted hexagonal boron nitride on Ir(110)

Camiel van Efferen, Joshua Hall, Nicolae Atodiresei +9
Two new ultimately thin vanadium rich 2D materials based on VS2 are created via molecular beam epitaxy and investigated using scanning tunneling microscopy, X-ray photoemission spe…
Metal-insulator transition in monolayer MoS via contactless chemical doping
Camiel van Efferen, Clifford Murray, Jeison Fischer +4
Much effort has been made to modify the properties of transition metal dichalcogenide layers via their environment as a route to new functionalization. However, it remains a challe…
Single-crystal graphene on Ir(110)
Stefan Kraus, Felix Huttmann, Jeison Fischer +12
A single-crystal sheet of graphene is synthesized on the low-symmetry substrate Ir(110) by thermal decomposition of CH at 1500 K. Using scanning tunneling microscopy, low-e…
