利用皮秒声学技术，我们测量了在 GaAs 上生长的微米厚闪锌矿（立方）GaN 外延膜的基本弹性和光学特性。我们提供声速、c11 弹性常数和折射率的低温值。我们的弹性常数值与立方 GaN 的理论计算非常一致（Wright 1997 J. Appl. Phys. 82 2833）。
Using the technique of picosecond acoustics, we measure the basic elastic and optical properties of a micrometre-thickness zinc-blende (cubic) GaN epitaxial film grown on GaAs. We provide low temperature values of the speed of sound, c11 elastic constant and refractive index. Our value of the elastic constant is in good agreement with the theoretical calculations for cubic GaN (Wright 1997 J. Appl. Phys. 82 2833).
