摘要
The films of corundum structure Al2O3 were successfully deposited on gold foil with pre-deposited α-Al2O3 seeds at low-temperature by reactive RF (Radio Frequency) sputtering with Al+α-Al2O3(15% α-Al2O3) target. The surface morphology, phase constituent and chemical composition of the as-deposited films were characterized by SEM, GIXRD and EDS. Results show that films of single α-Al2O3 with corundum-like crystallographic structure could be deposited at 560℃ on Si(100) substrate by reactive sputtering with Al+α-Al2O3 as composite target, while the substrate temperature even could be reduced to 500℃ for gold foil with pre-deposited α-Al2O3 seeds (the density of α-Al2O3 seeds is ~106/cm2) by reactive sputtering with pure Al as target. The results of the above two deposition methods proved that α-Al2O3 seeds may be favorable for the deposition of single phase α-Al2O3 films on the substrate at lower temperature. © 2022, Editorial Office of Chinese Journal of Materials Research.
