Abstract
The influence of S doping on the structural, electronic, and photocatalytic properties of the ZnO(101¯0) surface has been investigated by using the GGA+U method. We found that the doping with S atoms is energetically favored. The calculated DOS curves show that the S doping leads to the appearance of new electronic levels in the forbidden band. Consequently, the electronic structures and properties of the ZnO (101‾0) surface may be greatly affected. Furthermore, we found that the work function of the ZnO (101‾0) surface was decreased after doping with sulfur. This decrease in work function is accompanied by an increase in the band gap. The suitability of the S-doped ZnO (101‾0) surface for photocatalytic applications was also discussed and compared to the case of the O-deficient surface. We found that the formation of the SO-VO defect may enhance the photocatalytic properties of the ZnO (101‾0) surface.
