Abstract

We report the first use of the non-stoichiometric perovskite MAPbI₃ film for both NH₃ and HCl detection depending on different changes in the trend of the film resistance, in which moderate excess PbI₂ can enhance the sensing performance, due to the highly active PbI-terminated surface of MAPbI₃ crystals with abundant iodine vacancies.
