The aim of the project is the understanding of superficial reactions occurring in tin oxide under various chemical and temperature conditions which will lead to the design of gas sensing devices with improved performance. Moreover, novel gas sensing devices will be developed based on the physical properties of doped tin oxide. Electronic gas sensing devices, mostly based on tin oxide, have existed for decades, however these devices have never been widely used in portable and in building alarm systems for several reasons: 1) relatively large amounts of power are needed for their operation, 2) their sensitivity and selectivity is limited and 3) their repeatability, i.e., their ability to return to the initial state after exposure to the target gas, is limited. The impact of this project will be to improve gas sensing devices by considering the miniaturizarion of devices to the nanoscale, which will lead to the lowering of energy consumption to acceptable limits.
Dr. Maria Vasilopoulou received her degree in Physics from the University of Athens and her PhD degree on micro-lithography processes from the National Technical University of Athens in 2002. She was a research associate at NCSR Demokritos (2002-2006) and a professor on contract at TEI Piraeus (2006-2012). She is presently a Main Researcher at NCSR Demokritos. Her research activity focuses on the area of the organic optoelectronic devices and mainly on organic/organic and organic/inorganic interfaces characterization for organic light emitting diodes, organic photovoltaics and perovskite solar cells. Her interests include design and synthesis of metal oxides and alloys in several forms and oxidation states as well as structural, optical and electronic characterization of several nanomaterials.
