摘 要:Indium doped Zn O films were grown on quartz glass substrates by radio frequency magnetron sputtering from powder targets. Indium content in the targets varied from 1at% to 9at%. In doping on the structure, optical and electrical properties of Zn O thin films were studied. X-ray diffraction shows that all the films are hexagonal wurtzite with c-axis perpendicular to the substrates. There is a positive strain in the films and it increases with indium content. All the films show a high transmittance of 86% in the visible light region. Undoped Zn O thin film exhibits a high transmittance in the near infrared region. The transmittance of indium doped Zn O thin films decreases sharply in the near infrared region, and a cut-off wavelength can be found. The lowest resistivity of 4.3×10^(-4) Ω·cm and the highest carrier concentration of 1.86×10^(21) cm^(-3) can be obtained from Zn O thin films with an indium content of 5at% in the target.Indium doped Zn O films were grown on quartz glass substrates by radio frequency magnetron sputtering from powder targets.
