Post Doctoral Researchers
Andreas studied physics at the Humboldt-Universität zu Berlin and did his Bachelor about X-ray characterization of condensed matter and his Master about electrical characterization of thin films in 2012 and 2013, respectively. Afterwards, he worked as a research assistant at the Humboldt-Universität zu Berlin for 16 months focusing on teaching and maintaining the labs. From 2015 to 2019 he did his PhD research at the Leibniz-Institute for crystal growth about the optical and electrical characterization of β-Ga2O3 and the further development of this material. He finally received his Dr. rer. nat. from the Humboldt-Universität zu Berlin in experimental physics in 2019. Andreas joined Prof. Siddharth Rajan’s group in January 2020 to bring in his expertise about material growth and characterization, and to expand his knowledge about devices by integrating β-Ga2O3 in high power electronics.
Zane Jamal-Eddine received his B.S. in Electrical & Electronic Engineering from The Ohio State University, in 2016. He joined Prof. Rajan’s group as an undergraduate in 2014 , and now he is a PhD candidate. His research interests include Nitride MBE growth and improvement of efficiency in deep-ultraviolet LED devices.
