Optimizing the physical properties of the semiconductor ZnO (Zinc Oxide) can be done through the addition of impurities, also known as doping. In this study, sulfur-doped ZnO (S-ZnO) nanorod thin films have been synthesized using the seed-mediated hydrothermal method. This method was carried out in two steps, i.e. the seeding of ZnO on FTO substrate and the growing of S-ZnO on ZnO seeds under h…
