Mélissa Berteau-Rainville, who completed her PhD in Energy and Materials Science at INRS under the supervision of Professor Emanuele Orgiu, co-led a study with Professor Ingo Salzmann (Concordia University) and collaborators from York University. Published in Nature Materials, the research reports a promising new method for improving the performance of organic semiconductors. Article : Degradation-assisted doping of organic semiconductors enabled by Lewis acids

Why is this important?
The study introduces a new method for doping organic semiconductors, known as degradation-assisted doping (DAD), which significantly enhances their electrical conductivity. The researchers demonstrated that this approach can generate up to 100 times more charge carriers than conventional doping methods.
This discovery could support the development of higher-performance materials for applications in flexible electronics, optoelectronics, and thermoelectric technologies, while also paving the way for the use of less reactive molecules that may be less harmful to the environment.
In Their Own Words
Better understanding for better devices
“This method is not merely a fundamental discovery. Lewis acids are already used in the fabrication of electronic devices. Our findings now help explain why they work and identify pathways to further improve their efficiency.”
