Growth-controlled suppression of electrically active defects in CrSBr
Sara R. Tulchinsky, Sergii Grytsiuk, Shen van Hassel +7
In CrSBr, as in many crystalline materials, the type and density of defects are expected to strongly influence material behavior. Identifying the underlying atomic defect configura…
Defect complexes in CrSBr revealed through electron microscopy and deep learning
Mads Weile, Sergii Grytsiuk, Aubrey Penn +9
Atomic defects underpin the properties of van der Waals materials, and their understanding is essential for advancing quantum and energy technologies. Scanning transmission electro…
Epitaxial formation of ultrathin HfO2 on graphene by sequential oxidation
Zhenjing Liu, Qian Mao, Varun Kamboj +6
We demonstrate the formation of epitaxial, ultrathin hafnia (HfO2) on graphene. Monoclinic hafnia (m-HfO2) forms as the end of a series of sequential oxidation reactions. Starting…
Enhanced Ferromagnetism in Monolayer Cr2Te3 via Topological Insulator Coupling
Yunbo Ou, Murod Mirzhalilov, Norbert M. Nemes +20
Exchange-coupled interfaces are pivotal in exploiting two-dimensional (2D) ferromagnetism. Due to the extraordinary correlations among charge, spin, orbital and lattice degrees of…
The effect of surface oxidation and crystal thickness on magnetic properties and magnetic domain structures of Cr2Ge2Te6
Joachim Dahl Thomsen, Myung-Geun Han, Aubrey Penn +10
Van der Waals (vdW) magnetic materials such as Cr2Ge2Te6 (CGT) show promise for novel memory and logic applications. This is due to their broadly tunable magnetic properties and th…
Salt-assisted vapor-liquid-solid growth of one-dimensional van der Waals materials
Thang Pham, Kate Reidy, Joachim D. Thomsen +4
We have combined the benefits of two catalytic growth phenomena to form nanostructures of transition metal trichalcogenides (TMTs), materials that are challenging to grow in a nano…
Strain-tunable Berry curvature in quasi-two-dimensional chromium telluride
Hang Chi, Yunbo Ou, Tim B. Eldred +22
Magnetic transition metal chalcogenides form an emerging platform for exploring spin-orbit driven Berry phase phenomena owing to the nontrivial interplay between topology and magne…
Mechanisms of quasi-van der Waals epitaxy of 3D metallic nanoislands on suspended 2D materials
Kate Reidy, Joachim Dahl Thomsen, Hae Yeon Lee +6
Understanding structure at the interface between two-dimensional (2D) materials and 3D metals is crucial for designing novel 2D/3D heterostructures and improving the performance of…
Suspended graphene membranes to control Au nucleation and growth
Joachim Dahl Thomsen, Kate Reidy, Thang Pham +4
Control of nucleation sites is an important goal in materials growth: nuclei in regular arrays may show emergent photonic or electronic behavior, and once the nuclei coalesce into…
