Elastic Constants of Single-Crystal Aluminum Antimonide

Abstract
The ultrasonic cw resonance technique was used to measure the adiabatic elastic constants of single‐crystal aluminum antimonide at 27°C. The values for the elastic stiffness constants, in units of 1011 d/cm2, are: c11 = 8.939, c12 = 4.427, and c44 = 4.155. A theoretical density of 4.36 g/cc was used. The values of c11 and c44 for single crystal GaSb obtained by the cw resonance technique are compared with previous values obtained by pulse‐echo techniques.
