Self-introduction
I employ a wide range of material synthesis techniques—from single-crystal growth to molecular beam epitaxy (MBE)—to fabricate magnetic materials, superconductors, topological materials, and their heterostructures. Using angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling spectroscopy (STS), I directly visualize the electronic states that govern their physical properties, aiming to pioneer innovative materials and explore novel quantum phases. Visitors are always welcome.
