Photodiodes are key components in opto-electronic systems. Two-dimensional (2D) rhenium diselenide (ReSe2) offers new prospects in such devices due to its thickness-independent, moderate, and direct p type bandgap. We show here that the physisorption of oxygen plays an instrumental role in chemical doping of the ReSe2, as it enhances the positive charge carrier conductivity.
