摘要

The P-Ga codoping ZnO thin firms have been prepared on sapphire substrates by magnetron sputtering. Structural, optical and electrical properties of ZnO film were investigated using X-ray diffraction meter, transmittance spectra and resistivity, respectively. The obtained films were polycrystalline with the hexagonal structure, and a preferred orientation (0002) with the c-axis perpendicular to the substrates. The ZnO thin films became P- type after annealing. We have observed a room resistivity of 0.37 Ω cm and a carrier concentration of 1.6 x 10~(18) cm~(-3) in P-type ZnO film.
