Three-dimensional imaging of oxygen dopant distribution in SrCuO by electron ptychography
Hongbin Yang, Jinkwon Kim, Desheng Ma +3
Oxygen dopants play a critical role in tuning the properties of cuprate superconductors, yet it is challenging to visualize them at the atomic scale. Here, we use multislice electr…

Topotactic oxidation of Ruddlesden-Popper nickelates reveals new structural family: oxygen-intercalated layered perovskites
Dan Ferenc Segedin, Jinkwon Kim, Harrison LaBollita +20
Layered perovskites such as the Dion-Jacobson, Ruddlesden-Popper, and Aurivillius families host a wide range of correlated electron phenomena, from high-temperature superconductivi…

Superconducting vacancy-ordered rock-salt NbO films
Jeong Rae Kim, Sandra Glotzer, Evan Krysko +5
We report molecular beam epitaxy synthesis of vacancy-ordered rocksalt NbO thin films which display superconductivity. A comparative study of substrates identifies AlO (000…
