The goal of the research in our group is to understand novel materials. Particularly, we are interested in complex quantum materials and their microstructures.

We studies various highly correlated electron systems, such as high-temperature superconductors, Mott insulators, magnetic materials, low dimensional systems, etc.

For example, we synthesize single crystals by flux or floating zone method, measure their structural, chemical, and physical properties with XRD, TEM, EDX, PPMS/MPMS, and study their electronic structure with angle resolved photoemission spectroscopy (ARPES) at home based instrument and at various synchrotrons around the world, and/or with scanning tunneling microscopy and spectroscopy (STM/STS).

We also design and create novel materials with molecular beam epitaxy (MBE), and oxide MBE, then study them with ARPES/STM/STS and various other in situ techniques. We found that there are a lot to explore and discover at the interface of the complex quantum materials.
