The surface morphology and structure of (0001) sapphire substrates subjected to thermochemical nitridation in a mixture of N2, СО, and Н2 gases are investigated by electron and probe microscopy and X-ray and electron diffraction. It is shown that an aluminum nitride layer is formed on the substrate surface and heteroepitaxial ZnO films deposited onto such substrates by magnetron sputtering have a higher quality when compared with films grown on sapphire.
