We theoretically and numerically investigated procedures of accurately determining the acoustical physical constants of the piezoelectric hexagonal (class 6mm) crystals using bulk-wave velocities and leaky surface-acoustic-wave (LSAW) velocities by the ultrasonic microspectroscopy (UMS) technology. Taking ZnO as an example, selection of proper propagation modes and directions for eight velocity measurements was discussed for accurate determination of five elastic constants c11E, c12E, c13E, c33E, and c44E, and three piezoelectric constants e15, e31, and e33, in addition to measurements of two dielectric constants ε11S and ε33S and density ρ. Using only bulk-wave velocities measured for Y-cut, Z-cut, and several rotated Y-cut crystalline plane specimens could provide the best determination accuracies for the constants c13E, c33E, e31, and e33, and favorable determination accuracies using several sets of two rotated Y-cut crystalline plane specimens such as (101) and (102). Conductive specimens of (001) and (102) with a resistive (103) specimen made bulk-wave measurements simpler, resulting in much improved determination accuracies. Additional use of LSAW velocity with one conductive (001) specimen enabled simplifying the accurate determination procedures with acceptable accuracy for c13E. Measurements of bulk-wave velocities and LSAW velocities for only two resistive Y-cut and Z-cut specimens could determine all the constants with some deteriorations in accuracy especially for e31 and e33, but this was useful for preliminary determination of the constants for the precious crystals. |
