Topology-Driven Vibrations in a Chiral Polar Vortex Lattice
Eric R. Hoglund, Harrison A. Walker, Peter Meisenheimer +13
The ordering of magnetic or electric dipoles leading to real-space topological structures is at the forefront of materials research as their quantum mechanical nature often lends i…
Manipulating chiral-spin transport with ferroelectric polarization
Xiaoxi Huang, Xianzhe Chen, Yuhang Li +28
A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum of a spin wave, introduced more t…
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…
A room temperature polar ferromagnetic metal
Hongrui Zhang, Yu-Tsun Shao, Rui Chen +15
The advent of long-range magnetic order in non-centrosymmetric compounds has stimulated interest in the possibility of exotic spin transport phenomena and topologically protected s…
Electric Field Control of Chirality
Piush Behera, Molly A. May, Fernando Gómez-Ortiz +18
Polar textures have attracted significant attention in recent years as a promising analog to spin-based textures in ferromagnets. Here, using optical second harmonic generation bas…
Corrosion Resistance of Sulfur-Selenium Alloy Coatings
Sandhya Susarla, Govind Chilkoor, Yufei Cui +14
Despite decades of research, metallic corrosion remains a long-standing challenge in many engineering applications. Specifically, designing a material that can resist corrosion bot…
Differences in the Mechanical Properties of Monolayer and Multilayer WSe2/MoSe2
Y. M. Jaques, P. Manimunda, Y. Nakanishi +7
Transition metal dichalcogenides are 2D structures with remarkable electronic, chemical, optical and mechanical properties. Monolayer and crystal properties of these structures hav…
Quaternary two-dimensional (2D) transition metal dichalcogenides (TMDs) with tunable bandgap
Sandhya Susarla, Alex Kutana, Jordan A. Hachtel +7
Alloying/doping in two-dimensional material has been important due to wide range band gap tunability. Increasing the number of components would increase the degree of freedom which…
