Depending on the calcination temperatures, SnS₂-based photoelectrodes can either retain their n-type nature with greatly enhanced anodic photocurrent density (ca. 1.2 mA cm⁻² at 0.8 V vs. Ag/AgCl) or be completely converted into p-type SnS to generate approximately 0.26 mA cm⁻² cathodic photocurrent density at −0.8 V vs. Ag/AgCl. The dominance of sulfur and tin vacancies are found to account for the dramatically different photoelectrochemical behaviors of n-type SnS₂ and p-type SnS photoelectrodes. In addition, the band structures of n-type SnS₂ and p-type SnS photoelectrodes are also deduced, which may provide an effective strategy for developing SnS₂/SnS films with controllable energy-band levels through a simple calcination treatment.]]> Sat 24 Mar 2018 07:35:09 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28871 Mon 20 Nov 2023 15:46:57 AEDT ]]>
