Solution-processed ultraviolet photodetectors based on colloidal ZnO nanoparticles.
TL;DR: The photocurrent of the device is associated with a light-induced desorption of oxygen from the nanoparticle surfaces, thus removing electron traps and increasing the free carrier density which in turn reduces the Schottky barrier between contacts and ZnO nanoparticles for electron injection.
