Visualizing the breakdown of the quantum anomalous Hall effect
George M. Ferguson, Run Xiao, Anthony R. Richardella +3
The creation of topologically non-trivial matter across electronic, mechanical, cold-atom, and photonic platforms is advancing rapidly, yet understanding the breakdown of topologic…
Imaging signatures of edge currents in a magnetic topological insulator
G. M. Ferguson, Run Xiao, Anthony R. Richardella +3
Magnetic topological insulators (MTIs) host topologically protected edge states, but the role that these edge states play in electronic transport remains unclear. Using scanning su…
Interface-Induced Superconductivity in Magnetic Topological Insulator-Iron Chalcogenide Heterostructures
Hemian Yi, Yi-Fan Zhao, Ying-Ting Chan +24
When two different electronic materials are brought together, the resultant interface often shows unexpected quantum phenomena, including interfacial superconductivity and Fu-Kane…
Influence of magnetic and electric fields on universal conductance fluctuations in thin films of the Dirac semi-metal Cd3As2
Run Xiao, Saurav Islam, Wilson Yanez +6
Time-reversal invariance and inversion symmetry are responsible for the topological band structure in Dirac semimetals. These symmetries can be broken by applying an external magne…
Integer quantum Hall effect and enhanced g-factor in quantum confined Cd3As2 films
Run Xiao, Junyi Zhang, Juan Chamorro +6
We investigate the integer quantum Hall effect in Cd3As2 thin films under conditions of strong to moderate quantum confinement (thicknesses of 10 nm, 12 nm, 15 nm). In all the film…
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…
