Stefan Stefanov

New Materials Group, University of Vigo, Spain



Stefan hails from Bulgaria. He has earned Bachelor and Master degrees in Engineering Physics from the University of Oldenburg, Germany. Before starting his PhD in New Materials Group at the University of Vigo, Spain he has already spent 2 years there investigating deposition of biomaterials using lasers and light trapping polymer substrates for solar cells. While his current work focuses on synthesis and characterization of Group IV alloys (SiGeC, SiGe, GeSn, SiGeSn, GePb), mostly orientated towards bandgap engineering and optical properties optimization, his non-work interests range widely, everything from numerical simulations to Linux networking.

Mr. Stefanov has been a very motivated, committed and demanding student, always wishing to learn more and to deepen in his knowledge, both at theoretical as well as technical level. He has accepted the challenge to work in a very demanding field according to his academic background, and has achieved the goal to work independently at the pulsed laser deposition system. He has even contributed to technically improve the experiment. His performance in our group has been very good. - Betty Leon
