Electron Physics

The Electron Physics group is part of the Department of Electronics and Nanoengineering, Aalto University. Our research and education is focused on semiconductor materials and device physics. Our interests cover the whole scientific spectrum from fundamental physical phenomena to the search for cutting-edge applications in collaboration with leading industries. The current research activities include silicon-based photovoltaics and photodetectors, advanced characterization and nanofabrication techniques as well defect engineering in silicon. In addition to extensive facilities at Micronova Nanofabrication Centre, we use global research infrastructures in collaboration with our university and industry partners.
