Superconducting fourfold Fe (Te, Se) film on sixfold magnetic MnTe via hybrid symmetry epitaxy

X Yao, AR Mazza, MG Han, HT Yi, D Jain… - Nano Letters, 2022 - ACS Publications
Epitaxial Fe (Te, Se) thin films have been grown on various substrates but never been grown
on magnetic layers. Here we report the epitaxial growth of fourfold Fe (Te, Se) film on a …

Atomic-Layer-Controlled Magnetic Orders in MnBi2Te4–Bi2Te3 Topological Heterostructures

X Yao, Q Cui, Z Huang, X Yuan, HT Yi, D Jain… - Nano Letters, 2024 - ACS Publications
The natural van der Waals superlattice MnBi2Te4–(Bi2Te3) m provides an optimal platform
to combine topology and magnetism in one system with minimal structural disorder. Here …

Magneto-optical Effects of an Artificially Layered Ferromagnetic Topological Insulator with a TC of 160 K

X Han, HT Yi, S Oh, L Wu - Nano Letters, 2024 - ACS Publications
Magnetic topological insulators are a fertile platform for studying the interplay between
magnetism and topology. The unique electronic band structure can induce exotic transport …

From classical to quantum regime of topological surface states via defect engineering

M Salehi, X Yao, S Oh - SciPost Physics Lecture Notes, 2022 - scipost.org
Since the notion of topological insulator (TI) was envisioned in late 2000s, topology has
become a new paradigm in condensed matter physics. Realization of topology as a generic …
