Analysis of external and internal disorder to understand band-like transport in n-type organic semiconductors
Marc-Antoine Stoeckel, Yoann Olivier, Marco Gobbi +18
Charge transport in organic semiconductors is notoriously extremely sensitive to the presence of disorder, both internal and external (i.e. related to the interactions with the die…
Quantitative insights into the phase behaviour and miscibility of organic photovoltaic active layers from the perspective of neutron spectroscopy
Mohamed Zbiri, Peter A. Finn, Christian B. Nielsen +1
We present a neutron spectroscopy based method to study quantitatively the partial miscibility and phase behaviour of an organic photovoltaic active layer made of conjugated polyme…
Effect of substituting non-polar chains with polar chains on the structural dynamics of small organic molecule and polymer semiconductors
Anne A. Y. Guilbert, Zachary S. Parr, Theo Kreouzis +5
The processability and optoelectronic properties of organic semiconductors can be tuned and manipulated via chemical design. The substitution of the alkyl side chains by oligoether…
Probing dynamics of water mass transfer in organic porous photocatalyst water-splitting materials by neutron spectroscopy
Mohamed Zbiri, Catherine M. Aitchison, Reiner S. Sprick +2
The quest for efficient and economically accessible cleaner methods to develop sustainable carbon-free energy sources induced a keen interest in the production of hydrogen fuel. Th…
Freeing electrons from extrinsic and intrinsic disorder yields band-like transport in n-type organic semiconductors
Marc-Antoine Stoeckel, Yoann Olivier, Marco Gobbi +15
Charge transport in organic semiconductors is notoriously extremely sensitive to the presence of disorder, both intrinsic and extrinsic, especially for n-type materials. Intrinsic…
Mapping Microstructural Dynamics up to the Nanosecond of the Conjugated Polymer P3HT in the Solid State
Anne A. Y. Guilbert", Mohamed Zbiri", Peter A. Finn +6
We present a detailed study of the structure-dynamics relationship of regio-regular and regio-random PEHT using different neutron scattering techniques. Deuteration is employed to…
