More details: In this study, the effects of an (NH4)2Sx treatment on the surface work function (SWF) and roughness of indium?��tin-oxide (ITO) have been investigated. From the observed X-ray photoelectron spectroscopy results, optical transmittance measurements, atomic force microscopy measurements and four-point probe measurements, it is suggested that the surface chemical changes and an increase in the sheet resistance had strong effects on the \{SWF\} of ITO. We find that the S occupation of oxygen vacancies near the \{ITO\} surface after (NH4)2Sx treatment may result in a marked increase in the \{SWF\} and a slight increase in the surface roughness.
