Title: Prospects for nanowires: From nanomaterials to nanodevices.
Speaker: Professor Harry Eugen Ruda
Time: 10:00am, 20th June,2018
Address:Communication Building 818 Conference Room, Shahe Campus, UESTC.
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. 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. 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 is a Fellow of the Royal Society of Canada, Fellow of Institute of Physics and Fellow of the Institute of Nanotechnology.
The presentation discusses aspects of our research in nanowire optoelectronics beginning from a basic introduction to nanowires and their properties. The elements of how they are grown are introduced. Next we discuss how efficient light emitters and detectors can be made from such materials and what controls their performance. The factors controlling their behaviour are explained as well as how these materials can provide a robust platform for sensin
