An unusual continuous paramagnetic-limited superconducting phase transition in 2D NbSe
Egon Sohn, Xiaoxiang Xi, Wen-Yu He +9
Time reversal and spatial inversion are two key symmetries for conventional Bardeen-Cooper-Schrieffer (BCS) superconductivity. Breaking inversion symmetry can lead to mixed-parity…
Spin transistor built on 2D van der Waals heterostructures
Shengwei Jiang, Lizhong Li, Zefang Wang +2
Spin transistors (whose on-off operation is achieved by electric-field-controlled spin orientation 1), if realized, can revolutionize modern electronics through the implementation…
Electric-field switching of two-dimensional van der Waals magnets
Shengwei Jiang, Jie Shan, Kin Fai Mak
Controlling magnetism by purely electrical means is a key challenge to better information technology1. A variety of material systems, including ferromagnetic (FM) metals2,3,4, FM s…
Valley-selective exciton bistability in a suspended monolayer semiconductor
Hongchao Xie, Shengwei Jiang, Jie Shan +1
We demonstrate robust power- and wavelength-dependent optical bistability in fully suspended monolayers of WSe2 near the exciton resonance. Bistability has been achieved under cont…
Controlling magnetism in 2D CrI3 by electrostatic doping
Shengwei Jiang, Lizhong Li, Zefang Wang +2
The atomic thickness of two-dimensional (2D) materials provides a unique opportunity to control material properties and engineer new functionalities by electrostatic doping. Electr…
