Catalyzing n-doping
Transition metal nanoparticles catalysis maximizing n-doping efficiency
Electrical doping, i.e., inducing p- or n-type conductivity by adding a dopant, is of fundamental importance for device physics of semiconductors and is used in about every commercially produced device. For organic semiconductors, the conductivity is intrinsically low (typically 10−4–10−8 S/cm) due to the mostly amorphous nature, the weak coupling between molecules, and the low number of free charge carriers in the presence of large energy gaps.
