Graduate Student Researcher, Materials
Arturo Juan earned his bachelor’s degree in chemical engineering from the University of Southern California, then earned his master’s degree in electrical and computer engineering from UCSB. He worked in industry prior to entering the Materials PhD Program. Juan is advised by Steven DenBaars, a distinguished professor of materials and electrical and computer engineering. The focus of his research is on the epitaxial growth, processing, and characterization of wide-bandgap semiconductors for optoelectronic devices. According to Juan, working to improve the efficiency of materials that emit light could pave the way, for next-generation technologies having applications in optical communication, sensors, lighting, and quantum computing.
