CuCrCaO2 films were prepared by sol-gel.The effect of Ca-doping on the formation and electrical properties of the films with different environments and annealing temperatures was investigated.The CuCr1-xCaxO2(x=0,0.01,0.03,0.05,0.07)films are annealed at 1 100 ℃ in N2,XRD shows at low Ca concentration, the films have good crystallinities,lattice constant a,c and average grain size n increase with Ca concentration;at high Ca concentration impurity phases generate,makes a,c,n smaller,the results are identical with X-ray Diffraction(XRD).Besides,3%Ca hierarchical-mixed-spin-coating films are annealed quickly with different temperatures in air and N2 respectively.XRD shows hierarchical-mixed-spin-coating leads CuCrCaO2 to single crystal growth in N2 and has more obvious preferred orientation with higher annealed temperature.Using Hall instrument to measure films’ electrical properties with different Ca concentrations. The best conductivity is 1.22×10-1S/cm when x=0.03,which is three orders of magnitude higher than not doped films.It is shown that Ca doping helps to improve and the conductivity,the corresponding carrier mobility is 1.77 × 1018 cm-3,which means the material is P type structure.
