摘要: Abstract AlN films have been epitaxially grown onto (0001) sapphire substrates, for the first time, by electron cyclotron resonance plasma-assisted chemical vapor deposition using an AlBr 3 H 2 N gas mixture at substrate temperature as low 650°C. This method of film growth was shown to lead good epitaxial with a very smooth surface morphology. X-ray diffraction analysis showed that c -plane parallel sapphire. pole-figure [1210] direction is [1010] The further verified reflection high energy diffraction.
