Institute for Pure and Applied Physical Sciences - Faculty Dmitri N. Basov Ph.D., Physics Professor of Physics Research Areas Spectroscopic study of novel electronic materials In our research we employ infrared spectroscopy to investigate novel physics of novel electronic and magnetic materials. "Infrared" here is used colloquially since in fact our instruments allow us to cover much broader frequency range extending continuously from sub-THz to UV light. Current research directions include: Physics of strongly correlated electron systems Magnetic semiconductors Organic electronics Electromagnetic metamaterials Versatility of infrared and optical methods can be appreciated from a quick inspection of characteristic energy scales in solids which all fall in the frequency range that can be covered using a series of instruments available in our group. Development of novel spectroscopic instrumentation is an integral part of our research effort. For more information, visit http://infrared.ucsd.edu Selected Recent Publications Z. Q. Li, E. A.
