ResumoExposure to hυ > 3 eV light of amorphous InOx films in vacuum or an inert gas causes outdiffusion of oxygen and an increase in conductivity to more than 5×102 Ω−1cm−1. The same films can be reoxidized, for example by ozone, to obtain conductivities less than 10−4 Ω−1cm−1 at 300 K. Photoreduction and oxidation can change the conduction properties of one and the same film in a reproducible manner.
