Research Interests
Dr. Kwon's research interests are in experimental condensed matter and materials physics. Her research is mainly centered around perovskite oxide materials. She has been involved in thin film and multilayer fabrications, the characterization of structural and physical properties, and novel device developments using perovskite oxides. She is currently developing a variable temperature scanning laser microscope (VTSLM) as a new characterization instrument. VTSLM measures local optical response, and that can be related non-uniformities responsible to reduce the performance of materials.
