Evolution from Topological Dirac Metal to Flat-band-Induced Antiferromagnet in Layered KxNi4S2 (0<=x<=1)
Hengdi Zhao, Xiuquan Zhou, Hyowon Park +17
Condensed matter systems with coexisting Dirac cones and flat bands, and a switchable control between them within a single system, are desirable but remarkably uncommon. Here we re…

Semiconducting behaviors at epitaxial Ca0.5TaO3 interfaces
Guangdong Nie, Guanghui Han, Shengpu Huang +10
Emergent phenomena take place in symmetry-breaking systems, notably the recently discovered two-dimensional electron gas and its tunable superconductivities near the KTaO3 interfac…
