Enhanced photocurrent and responsivity of PbS quantum Dot/ZnO nanoparticle films with amine passivation

This study investigated a combination of PbS quantum dots (QDs) and ZnO nanoparticles (NPs) layers in photodiodes for photodetection. Oxygen vacancies in ZnO NPs have been known to be recombination trap sites, hindering carrier transportation. We used various amines to passivate the oxygen vacancy o...
