Abstract

We have developed a direct method of measuring the shear strain using a laser-based interferometer. The method was applied to the measurement of the d₁₅ coefficient for wurtzite GaN and A1N. A value for d₁₅ of 3.6 ± 0.2pm V^-1 for AIN has been obtained, in good agreement with values quoted in the literature. The value of d₁₅ for GaN has also been measured to be 3.1 ± 0.2pm V^-1.
