Journal of Materials Science and Nanotechnology

Harry Ruda is Director of the Centre for Advanced Nanotechnology, the Stanley Meek Chair in Nanotechnology, and Professor of Applied Science and Engineering at the University of Toronto. The Centre is Canada’s first nanotechnology centre. From 1984 to 1989 he was a senior scientist at 3M Corporation, developing some of the first models for electronic transport and optical properties of wide bandgap II-VI semiconductors, while being a key member of the blue laser team. From 1982 to 1984 he developed one of the first theories for electron transport in selectively doped two dimensional electron gas heterostructures while working as an IBM postdoctoral fellow. From 1979 to 1982 he worked on optical and transport properties of II-VI based infrared detector materials and obtained his PhD from MIT in 1982. Professor Ruda has published over 250 publications in international refereed journals (with over 2,700 SCI citations), has co-authored 4 books and has 14 patents. Professor Ruda’s research interests focus on the fabrication and modeling of quantum functional nanostructures with applications in the fields of nanoelectronics and nanophotonics. Some notable contributions include one of the first theories of carrier transport in selectively doped quantum heterostructures, theories for the non-linear optical response of asymmetric quantum heterostructures, models for the dynamics of quantum neural networks, as well as reports on the preparation of self-assembled quantum heterostructures by molecular beam epitaxy and using ion beam processing for photonic crystal device development. In addition, his contributions include the development of novel characterization techniques for semiconductor and dielectric nanostructures (photonic crystals) based on pump and probe surface photovoltage measurements.
Harry Ruda is one of the founders of a Canadian National Centre of Excellence in Photonics. He serves on the National Science and Engineering Council of Canada and on other government panels including those of the DOE, EPA and NSF in the US, and the RAE and EPSRC in the UK. He also serves on the editorial boards of: Journal of Applied Physics, Applied Physics Letters, Journal of Nanoscience and Nanotechnology, Journal of Materials Science: Materials in Electronics, and the Nanotechnology Research Letters. He is a Fellow of the Royal Society of Canada, Fellow of Institute of Physics and Fellow of the Institute of Nanotechnology.
