Different concentration of ZnO:C thin films were deposited on quartz glass substrates by a radio-frequency (RF) magnetron sputtering technique. The structure, Raman and electrical properties of ZnO:C film were investigated by X-ray diffractometer, Raman scattering spectrum and Hall measurement system. Then, we explore the role of C in the ZnO:C film. The results indicate that all films perform the ZnO wurtzite structure with preferred c-axis orientation. The n-type conductivity enhances with the increase of C dopant, and the main explanation to be that C substitute for zinc site and act as donor.
