Changsub Kim

Changsub is a research staff developing state-of-the-art superconducting thin films and devices. Before coming to JPL, he studied how oxygen atoms/ions move inside and at the surface of metal oxides and controlled properties by electrochemically pumping oxygen into and out of the oxides.
