Uncovering polar vortex structures by inversion of multiple scattering with a stacked Bloch wave model
Steven E Zeltmann, Shang-Lin Hsu, Hamish G Brown +4
Nanobeam electron diffraction can probe local structural properties of complex crystalline materials including phase, orientation, tilt, strain, and polarization. Ideally, each dif…
Imaging the electron charge density in monolayer MoS2 at the Ångstrom scale
Joel Martis, Sandhya Susarla, Archith Rayabharam +15
Four-dimensional scanning transmission electron microscopy (4D-STEM) has recently gained widespread attention for its ability to image atomic electric fields with sub-Ångstrom spat…
Hyperspectral imaging of excitons within a moiré unit-cell with a sub-nanometer electron probe
Sandhya Susarla, Mit H. Naik, Daria D. Blach +9
Electronic and optical excitations in two-dimensional moiré systems are uniquely sensitive to local atomic registries, leading to materials- and twist-angle specific correlated ele…
Pervasive beyond room-temperature ferromagnetism in a doped van der Waals magnet: Ni doped FeGeTe with up to 478 K
Xiang Chen, Yu-Tsun Shao, Rui Chen +10
The existence of long range magnetic order in low dimensional magnetic systems, such as the quasi-two-dimensional (2D) van der Waals (vdW) magnets, has attracted intensive studies…
