Direct visualization of electronic transport in a quantum anomalous Hall insulator
G. M. Ferguson, Run Xiao, Anthony R. Richardella +3
A quantum anomalous Hall (QAH) insulator is characterized by quantized Hall and vanishing longitudinal resistances at zero magnetic field that are protected against local perturbat…
Crossover of Ising- to Rashba-Type Superconductivity in Epitaxial Bi2Se3/Monolayer NbSe2 Heterostructures
Hemian Yi, Lun-Hui Hu, Yuanxi Wang +15
A topological insulator (TI) interfaced with an s-wave superconductor has been predicted to host an unusual form of superconductivity known as topological superconductivity (TSC).…
ZrTe2/CrTe2: an epitaxial van der Waals platform for spintronics
Yongxi Ou, Wilson Yanez, Run Xiao +12
The rapid discovery of two-dimensional (2D) van der Waals (vdW) quantum materials has led to heterostructures that integrate diverse quantum functionalities such as topological pha…
Mapping the phase diagram of the quantum anomalous Hall and topological Hall effects in a dual-gated magnetic topological insulator heterostructure
Run Xiao, Di Xiao, Jue Jiang +11
We use magnetotransport in dual-gated magnetic topological insulator heterostructures to map out a phase diagram of the topological Hall and quantum anomalous Hall effects as a fun…
Spin and charge interconversion in Dirac semimetal thin films
Wilson Yanez, Yongxi Ou, Run Xiao +17
We report spin-to-charge and charge-to-spin conversion at room temperature in heterostructure devices that interface an archetypal Dirac semimetal, Cd3As2, with a metallic ferromag…
