Supercell formation in epitaxial rare-earth ditelluride thin films
Adrian Llanos, Salva Salmani-Rezaie, Jinwoong Kim +3
Square net tellurides host an array of electronic ground states and commonly exhibit charge-density-wave ordering. Here we report the epitaxy of DyTe on atomically flat MgO…
Direct visualization of surface spin-flip transition in MnBi4Te7
Wenbo Ge, Jinwoong Kim, Ying-Ting Chan +3
We report direct visualization of spin-flip transition of the surface layer in antiferromagnet MnBi4Te7, a natural superlattice of alternating MnBi2Te4 and Bi2Te3 layers, using cry…
Robust A-type order and spin-flop transition on the surface of the antiferromagnetic topological insulator MnBiTe
Paul M. Sass, Jinwoong Kim, David Vanderbilt +2
Here we present microscopic evidence of the persistence of uniaxial A-type antiferromagnetic order to the surface layers of MnBiTe single crystals using magnetic force micr…
Engineering Weyl phases and nonlinear Hall effects in T-MoTe
Sobhit Singh, Jinwoong Kim, Karin M. Rabe +1
MoTe has recently attracted much attention due to the observation of pressure-induced superconductivity, exotic topological phase transitions, and nonlinear quantum effects. Ho…
Negative piezoelectric response of van der Waals layered bismuth tellurohalides
Jinwoong Kim, Karin M. Rabe, David Vanderbilt
The polarization and piezoelectric response of the BiTe (=Cl, Br, and I) layered tellurohalides are computed from first principles. The results confirm a mixed ionic-covalent…
Ferromagnetic Anomalous Hall Effect in Cr-doped BiSe Thin Films via Surface-State Engineering
Jisoo Moon, Jinwoong Kim, Nikesh Koirala +3
The anomalous Hall effect (AHE) is a non-linear Hall effect appearing in magnetic conductors, boosted by internal magnetism beyond what is expected from the ordinary Hall effect. W…
