Physicochemical conditions and polishing suspension composition were established for polishing of AlN/sapphire templates obtained by thermochemical nitridation of sapphire. The use of the polishing suspension based on aerosil and KOH with pH 10.3 allowed to prepare the surface with a roughness Ra up...
