摘要: Aluminum nitride (AlN) films were grown on sapphire substrates by radio frequency magnetron sputtering in plasma containing a mixture of argon and nitrogen, using pure aluminum target. Surface morphology dependence the AlN growth conditions such as substrate temperature nitrogen concentration was investigated. c-axis preferred wurtzite film with surface roughness small 2.9 nm obtained at 100 °C 20%. The increased increasing concentration. correlation between discussed.
