Angle- and spin-resolved photoemission spectroscopy study of monolayer NbSe2

ORAL

Abstract

The coexistence of superconductivity and charge density wave (CDW) at low temperature makes NbSe2 an ideal system to study the interplay between superconductivity and CDW. When its thickness approaches to one single layer, the impact of spin-orbit coupling on the electronic structure of NbSe2 becomes more and more significant, leading to spin-valley locking and so-called “Ising superconductivity”. Here we report the electronic and spin structural studies of a monolayer NbSe2 thin film using Angle-resolved photoemission spectroscopy (ARPES) and Spin-Resolved ARPES.
