Characterizing the Structure of Topological Insulator Thin Films
Anthony Richardella, Abhinav Kandala, Joon Sue Lee +1
We describe the characterization of structural defects that occur during molecular beam epitaxy of topological insulator thin films on commonly used substrates. Twinned domains are…
Visualization of superparamagnetic dynamics in magnetic topological insulators
E. Lachman, A. F. Young, A. Richardella +10
Quantized Hall conductance is a generic feature of two dimensional electronic systems with broken time reversal symmetry. In the quantum anomalous Hall state recently discovered in…
Giant Anisotropic Magnetoresistance in a Quantum Anomalous Hall Insulator
A. Kandala, A. Richardella, S. Kempinger +2
When a three-dimensional (3D) ferromagnetic topological insulator thin film is magnetized out-of-plane, conduction ideally occurs through dissipationless, one-dimensional (1D) chir…
