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…
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…
