Direct observation of ultrafast long-range charge separation at polymer:fullerene heterojunctions
Françoise Provencher, Nicolas Bérubé, Anthony W. Parker +7
In polymeric semiconductors, charge carriers are polarons, which means that the excess charge deforms the molecular structure of the polymer chain that hosts it. This effect result…

Large electronic bandwidth in solution-processable pyrene crystals: The role of close-packed crystal structure
Francoise Provencher, Jean-Frederic Laprade, Gabrielle Simard +3
We examine the interdependence of structural and electronic properties of two substituted pyrene crystals by means of combined spectroscopic probes and density-functional theory ca…
