Abstract

The room-temperature elastic moduli

c_{ij}

of AgGa

S_{2}

have been determined using laser Brillouin scattering. This is the first determination of these moduli for any of the ternary compounds which crystallize with the chalcopyrite structure. From the Brillouin shifts the following values for the elastic moduli were obtained:

c_{11} = 8.79 \pm 0.05

c_{33} = 7.58 \pm 0.05

c_{44} = 2.41 \pm 0.05

c_{66} = 3.08 \pm 0.05

c_{12} = 5.84 \pm 0.05

, and

c_{13} = 5.92 \pm 0.06

, in units of

10^{11}
