Chiral, Electronically Decoupled Layers of 1T'-WS2 Topological Insulator via Neutral-Molecule Intercalation
Jiaze Xie, Fatmagül Katmer, Fang Yuan +9
Monolayer 1T'-WS2 is predicted to be a two-dimensional topological insulator, but its intrinsic electronic properties are masked by strong interlayer coupling in its metallic and s…
New Superconductors in the PtPbBi Structure Type
Lior Verbitsky, Amira Merino, Scott B. Lee +8
The quest for new superconductors is of both fundamental and technological importance. Recently, an artificial intelligence method correctly predicted PtPbBi to be a supercondu…
Tunable magnetotransport through kinetically hindered first-order phase transitions in an antiferromagnetic metal
Jaime M. Moya, Scott B. Lee, Sudipta Chatterjee +4
Controllable multilevel resistance states are of interest for memory technologies like neuromorphic computing, but robust materials platforms toward such behavior remain limited. H…
Stripping Symmetry: Electrochemical Oxidation to a Superconducting Polar Metal in Au2Pb0.914P2
Scott B. Lee, Stephanie R. Dulovic, Joseph W. Stiles +11
Polar metals and noncentrosymmetric superconductors are exceptionally rare, yet their broken inversion symmetry can give rise to emergent electronic phenomena including mixed singl…
New Crystal Structures Hide in Plain Sight: A Stress Test for AI-Guided Materials Discovery
Xin Zhang, Scott B. Lee, Sudipta Chatterjee +14
New types of crystal structures are discovered only rarely, and the artificial intelligence (AI) models now reshaping materials discovery have so far produced new chemical composit…
Measuring the Hall effect in hysteretic materials
Jaime M. Moya, Anthony Voyemant, Sudipta Chatterjee +4
Measurement of the Hall effect is a ubiquitous probe for materials discovery, characterization, and metrology. Inherent to the Hall measurement geometry, the measured signal is oft…
Bonding Interactions Can Drive Topological Phase Transitions in a Zintl Antiferromagnetic Insulator
Tanya Berry, Jaime M. Moya, David Smiadak +5
While 30% of materials are reported to be topological, topological insulators are rare. Magnetic topological insulators (MTI) are even harder to find. Identifying crystallogr…
