Dr K Radhakrishnan is an Associate Professor in the School of Electrical and Electronic Engineering at Nanyang Technological University, Singapore. He was the Principal Investigator for several major research projects related to the epitaxial growth of III-V Compound Semiconductors, devices and circuits over the years, primarily using arsenide and phosphide based material systems. His current research interests include MBE/MOCVD thin film growth and characterization of III-nitrides for various applications such as high power RF devices, UV detectors and gas sensors. His other research interests include synthesis and fabrication of oxide based thin film solar cells. He has authored and co-authored more than 200 international journal and conference papers and delivered invited talks at several international conferences. In 2007, he was one of the recipients of the prestigious Singapore’s Defense Technology Prize for his technological contributions in MMIC (microwave monolithic integrated circuits) R & D.
