Emergence of Chern metal in a moiré Kondo lattice

A Chern metal is a two-dimensional metallic state of matter carrying chiral edge states. We report the observation of a Chern metal at the onset of the magnetic Kondo breakdown in a frustrated moiré Kondo lattice--angle-aligned MoTe 2 /WSe 2 bilayers. The state is compressible an...

Stacking-Order-Dependent Electronic Properties of MoTe2/WSe2 Moire Bilayers

Abstract Transition metal dichalcogenide (TMD) moiré bilayers have realized a wide range of strongly correlated and topological phenomena. The physics in these materials is often sensitive to the interlayer stacking order. Polarization-resolved optical second harmonic generation...
