Abstract:
The discovery of high temperature superconductivity in infinite-layer (IL) and Ruddlesden-Popper (RP) nickelates has garnered significant interest, providing new avenues to explore the underlying mechanisms of unconventional high-Tc superconductivity. In this talk, I will present the atomic-precision synthesis of high-quality IL and RP nickelate thin films using oxide molecular beam epitaxy (MBE). By combining angle-resolved photoemission spectroscopy (ARPES), transport measurements, and theoretical calculations, we investigate the electronic structures and transport properties of these novel superconductors.
