Abstract
We have successfully grown high-quality AlN piezoelectric single crystal using the sublimation technique. Transparent crack-free boules of approximately 15 mm in diameter and 25 mm in length along the [0001] direction were obtained, with coloring from amber to dark brown depending on growth temperature. Full sets of material parameters of grown AlN and commercially available LiAlO2 bulk crystals were measured at room temperature. Temperature coefficients of the material parameters of LiAlO2 were also obtained in a temperature range from -70 to +50??C.
