Silicon-Germanium Alloys for Photovoltaic Applications

Professor Ammar Nayfeh was born in Urbana IL in 1979. He received his bachelor's degree from the University of Illinois Urbana Champaign in 2001 in electrical engineering and his master's degree in 2003 from Stanford University. Dr. Nayfeh earned a Ph.D. in electrical engineering from Stanford University in 2006. His research focused on heteroepitaxy of germanium on silicon for electronic and photonic devices. After his PhD, he joined Advanced Micro Devices as a researcher working in collaboration with IBM. After that he joined a silicon valley startup company, Innovative Silicon (ISi) in 2008. In addition, he was a part time professor at San Jose State University. In June 2010, he joined MIT as a visiting scholar and became a faculty member at the Masdar Institute currently Khalifa University. His research interest focuses on nanotechnology for future more efficient low power electronic and photonic devices. Professor Nayfeh is currently an associate professor in the Department Electrical Engineering and Computer Science (EECS) at Khalifa University. Professor Ammar Nayfeh has authored or co-authored over 100 publications, and holds three patents. He is a member of IEEE, MRS and Stanford Alumni Association. He has received the Material Research Society Graduate Student Award, the Robert C. Maclinche Scholarship at UIUC, and Stanford Graduate Fellowship. Dr. Sabina Abdul Hadi received her B.Sc. and M.Sc. Degrees in Electrical and Electronics Engineering from Eastern Mediterranean University, North Cyprus, and received an M.Sc. degree in Microsystems Engineering and PhD degree in Interdisciplinary Engineering from Masdar Institute (currently Khalifa University), Abu Dhabi, United Arab Emirates. Her PhD work focused on modeling and fabrication of low-cost III-V on Si multi-junction solar cells. Later, Dr. Abdul Hadi worked as a postdoctoral fellow at Khalifa University of Science and Technology on memristor based sensing applications. Dr. Abdul Hadi is currently working as an Assistant Professor at Electrical Engineering Departmentt, University of Dubai, Dubai, UAE She has co-authored more than 25 conference proceedings and scientific papers in ranked journals and international conferences. Her research interests include semiconductor physics, device modeling and fabrication, thin films and anti-reflective coating materials, emerging PV technologies, device characterization, among others.
