Our group is always looking for very motivated PhD students, postdocs and undergraduate researchers, with an excitement for semiconductor materials and devices. Students with a strong background/interest in semiconductor device physics, epitaxial growth, and micro/nanofabrication with a bachelors/masters degree in materials engineering, electrical engineering, physics (or related fields) can contact me. Please send a note (with CV) to sriramkrishnamoorthy@ucsb.edu , if you are interested in discussing your research interests with me. Due to high volume of emails, I might not be able to respond to every request. Thanks for your understanding and patience. We look forward to working with a diverse group of highly motivated graduate, undergraduate students and postdoctoral researchers.
