High temperature, gate-free quantum anomalous Hall effect with an active capping layer
Hee Taek Yi, Deepti Jain, Xiong Yao +1
Quantum anomalous Hall effect (QAHE) was discovered a decade ago, but is still not utilized beyond a handful of research groups, due to numerous limitations such as extremely low t…
Superconducting four-fold Fe(Te,Se) film on six-fold magnetic MnTe via hybrid symmetry epitaxy
Xiong Yao, Alessandro R. Mazza, Myung-Geun Han +4
Epitaxial Fe(Te,Se) thin films have been grown on various substrates but never been realized on magnetic layers. Here we report the epitaxial growth of four-fold Fe(Te,Se) film on…
Reaching the equilibrium state of frustrated triangular Ising magnet Ca3Co2O6
Ivan Nekrashevich, Xiaxin Ding, Fedor Balakirev +5
Ca3Co2O6 is a frustrated magnet consisting of a triangular arrangement of chains of Ising spins. It shows regular magnetization steps vs magnetic field every 1.2 T that are metasta…
Suppressing carrier density in (BixSb1-x)2Te3 films using Cr2O3 interfacial layers
Xiong Yao, Hee Taek Yi, Deepti Jain +1
Band structure engineering and interfacial buffer layers have been demonstrated as effective means to tune the Fermi level in topological insulators (TI). In particular, the charge…
Hybrid symmetry epitaxy of superconducting Fe(Te,Se) film on a topological insulator
Xiong Yao, Matthew Brahlek, Hee Taek Yi +4
It is challenging to grow an epitaxial four-fold compound superconductor (SC) on six-fold topological insulator (TI) platform due to stringent lattice-matching requirement. Here, w…
Spacer-layer-tunable magnetism and high-field topological Hall effect in topological insulator heterostructures
Xiong Yao, Hee Taek Yi, Deepti Jain +2
Controlling magnetic order in magnetic topological insulators (MTIs) is a key to developing spintronic applications with MTIs, and is commonly achieved by changing the magnetic dop…
