Imaging defects in two-dimensional crystals by convergent beam electron diffraction
Tatiana Latychevskaia, Pengru Huang, Kostya S. Novoselov
Convergent beam electron diffraction (CBED), recently demonstrated on two-dimensional (2D) materials, offers a number of interesting applications such as imaging atomic in- and out…
Untangling 3D atomic reconstruction in twisted bilayer 2D crystals via dark field transmission electron microscopy
Pankaj Kumar, Michel Bosman, Nikolai Lavrentev +4
Reconstruction of the atomic crystal structure in twisted 2D materials has been demonstrated to be responsible for multiple exciting phenomena in van der Waals heterostructures, fr…
Rashba engineering at van der Waals interfaces
Rahul Sharma, Soumya Mukherjee, Fatima Ibrahim +26
Two-dimensional transition metal dichalcogenide (TMD) interfaces offer a versatile platform for studying emergent quantum phenomena and enabling novel device functionalities. When…
A comparative study of perturbative and nonequilibrium Green's function approaches for Floquet sidebands in periodically driven quantum systems
Karun Gadge, Marco Merboldt, Michael Schüler +6
We compare two complementary theoretical approaches to compute and interpret Floquet sidebands in periodically driven quantum materials: a first-order perturbative approach (first-…
Generating unconventional spin-orbit torques with patterned phase gradients in tungsten thin films
Lauren J. Riddiford, Anne Flechsig, Shilei Ding +7
A key aim in spintronics is to achieve current-induced magnetization switching via spin-orbit torques without external magnetic fields. For this, the focus of recent work has been…
In-situ Straining of Epitaxial Freestanding Ferroic Films by a MEMS Device
Simone Finizio, Tim A. Butcher, Maria Cocconcelli +10
Mechanical strain can be used to control physical properties in materials. The experimental investigation of strain-induced effects at the nanoscale is of importance not only for i…
