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…

Two-dimensional spatial coherence of excitons in semicrystalline polymeric semiconductors: The effect of molecular weight
Francis Paquin, Hajime Yamagata, Nicholas J. Hestand +8
The electronic properties of macromolecular semiconductor thin films depend profoundly on their solid-state microstructure, which in turn is governed, among other things, by the pr…

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…
