Quantification of magnetic interactions in van der Waals heterostructures using Lorentz transmission electron microscopy and electron holography
Joachim Dahl Thomsen, Qianqian Lan, Nikolai S. Kiselev +4
Magnetic van der Waals (vdW) materials are promising for memory and logic applications because of their highly tunable magnetic properties and compatibility with vdW heterostructur…
Towards reliable electrical measurements of superconducting devices inside a transmission electron microscope
Joachim Dahl Thomsen, Michael I. Faley, Joseph Vimal Vas +6
Correlating structure with electronic functionality is central to the engineering of quantum materials and devices whose properties depend sensitively on disorder. Transmission ele…
The morphology and interface structure of titanium on graphene
Joachim Dahl Thomsen, Wissam A. Saidi, Kate Reidy +4
Titanium (Ti) is an adhesion and contact metal commonly used in nanoelectronics and two-dimensional (2D) materials research. However, when Ti is deposited on graphene (Gr), we obta…
Electric-Field Control of Magnetic Skyrmion Chirality in a Centrosymmetric 2D van der Waals Magnet
Myung-Geun Han, Joachim Dahl Thomsen, John P. Philbin +9
Two-dimensional van der Waals magnets hosting topological magnetic textures, such as skyrmions, show promise for applications in spintronics and quantum computing. Electrical contr…
Direct visualization of defect-controlled diffusion in van der Waals gaps
Joachim Dahl Thomsen, Yaxian Wang, Henrik Flyvbjerg +5
Diffusion processes govern fundamental phenomena such as phase transformations, doping, and intercalation in van der Waals (vdW) bonded materials. Here, we quantify the diffusion d…
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…
Single-photon detection using large-scale high-temperature MgB sensors at 20 K
I. Charaev, E. K. Batson, S. Cherednichenko +10
Ultra-fast single-photon detectors with high current density and operating temperature can benefit space and ground applications, including quantum optical communication systems, l…
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…
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…
Atomistic spin textures on-demand in the van der Waals layered magnet CrSBr
Julian Klein, Thang Pham, Joachim Dahl Thomsen +10
Controlling magnetism in low dimensional materials is essential for designing devices that have feature sizes comparable to several critical length scales that exploit functional s…
Direct Imaging and Electronic Structure Modulation of Moiré Superlattices at the 2D/3D Interface
Kate Reidy, Georgios Varnavides, Joachim Dahl Thomsen +7
The atomic structure at the interface between two-dimensional (2D) and three-dimensional (3D) materials influences properties such as contact resistance, photo-response, and high-f…
A general approach for the synthesis of two-dimensional binary compounds
Abhay Shivayogimath, Joachim Dahl Thomsen, David M. A. Mackenzie +7
Only a few of the vast range of potential two-dimensional materials have been isolated or synthesised to date. Typically, 2D materials are discovered by mechanically exfoliating na…
