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…
Atomic-Scale Detection of Néel Vector Switching in the Single-Layer A-type Antiferromagnet Cr2S3-2D
Affan Safeer, Calisa Dias, Mahdi Ghorbani-Asl +9
The detection of Néel vector switching in a single-layer A-type antiferromagnet marks an important step toward functional two-dimensional spintronics. Here, CrS-2D, grown…
Atomic-Scale Quantum Control of Single Spin Defects in a Two-Dimensional Semiconductor
Kwan Ho Au-Yeung, Wantong Huang, Johanna Matusche +15
Individual spin defects in solids are promising building blocks for quantum technologies, but their deterministic creation, individual addressability, and operation near surfaces r…
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…
