Organic semiconductors are materials with many promising properties compared to their inorganic counterparts such as high flexibility, biocompatibility, solution processability, and low cost. However, they have low conductivities, which we overcome by doping.
Here we demonstrate a new record conductivity for this kind of doped polymers and investigate the mechanisms which contribute to this high conductivity. These insights aid the design of new organic semiconductors with even higher performance.

This work was carried out in the group of Prof. Dr. Natalie Banerji.
