N2 - The AlN phase transition on the (0001) Al2O3 surface was investigated. It was experimentally estimated that the AlN formation rate as a function of temperature has a different character in two temperature regions. In the region of relatively low temperatures (T < 1210 K), the AlN formation rate is limited by chemical reactions. At higher temperatures (T > 1210 K), the formation of an ordered AlN phase is determined by a continuous two-dimensional phase transition within the filled AlN-lattice-gas cells formed on the sapphire surface. A three-parameter isotherm is proposed to describe the process. The observed phase transition in the AlN lattice gas is a continuous phase transition or a second-order transition.
