摘要

We report a photocurrent generation mechanism in the SnO ₂ thin film surface layer by the charged chemisorption O ions on the SnO ₂ thin film surface induced by O ₂ -annealing. A critical build-in electric field in the SnO ₂ surface layer resulted from the charged O ions on SnO ₂ surface prolongs the lifetime and reduces the recombination probability of the photo-excited electron-hole pairs by UV-laser irradiation (266 nm) in the SnO ₂ surface layer, which is the key for the photocurrent generation in the SnO ₂ thin film surface layer. The critical lifetime of prolonged photo-excited electron-hole pair is calculated to be 8.3 ms.
