Benoît Lessard and his team are developing carbon-based technologies which could lead to improved flexible phone displays, make robotic skin more sensitive and allow for wearable electronics that could monitor the physical health of athletes in real-time.
With the help of the Canadian Light Source (CLS) at the University of Saskatchewan (USask), a team of Canadian and international scientists have evaluated how thin film structure correlates to organic thin-film transistors performance.
Organic electronics use carbon-based molecules to create more flexible and efficient devices. The display of our smart phones is based on organic-LED technology, which uses organic molecules to emit bright light and others to respond to touch.
Lessard, the corresponding author of a recent paper published in ACS Applied Materials and Interfaces, is excited about the data his team has collected at the HXMA beamline. As Canada Research Chair in Advanced Polymer Materials and Organic Electronics and Associate Professor at the University of Ottawa in the Department of Chemical and Biological Engineering, Lessard is working on furthering the technology behind organic thin-film transistors. To improve on this technology the team is engineering the design and processing of phthalocyanines, molecules used traditionally as dyes and pigments.
