Journal ArticleDOI
Tightly bound excitons in monolayer WSe(2).
TL;DR: The result reveals significantly reduced and nonlocal dielectric screening of Coulomb interactions in 2D semiconductors and will have a significant impact on next-generation photonics and optoelectronics applications based on 2D atomic crystals.
Journal ArticleDOI
Ising pairing in superconducting NbSe2 atomic layers
Xiaoxiang Xi,Zefang Wang,Weiwei Zhao,Ju-Hyun Park,Kam Tuen Law,Helmuth Berger,László Forró,Jie Shan,Kin Fai Mak +8 more
TL;DR: In this article, the superconducting properties of NbSe2 as it approaches the monolayer limit are investigated by means of magnetotransport measurements, uncovering evidence of spin-momentum locking.
Journal ArticleDOI
Controlling magnetism in 2D CrI 3 by electrostatic doping
TL;DR: In this article, the magnetic properties of both monolayer and bilayer CrI3-graphene vertical heterostructures were demonstrated by electrostatic doping using CVD.
Journal ArticleDOI
Strongly enhanced charge-density-wave order in monolayer NbSe2
Xiaoxiang Xi,Liang Zhao,Zefang Wang,Helmuth Berger,László Forró,Jie Shan,Jie Shan,Kin Fai Mak +7 more
TL;DR: A combined optical and electrical transport study on the many-body collective-order phase diagram of NbSe2 down to a thickness of one monolayer opens up a new window for search and control of collective phases of two-dimensional matter, as well as expanding the functionalities of these materials for electronic applications.
Journal ArticleDOI
Controlling magnetism in 2D CrI3 by electrostatic doping
TL;DR: In monolayer CrI3, doping significantly modifies the saturation magnetization, coercive force and Curie temperature, showing strengthened/weakened magnetic order with hole/electron doping, and the result reveals a strongly doping-dependent interlayer exchange coupling, which enables robust switching of magnetization in bilayerCrI3 by small gate voltages.
