摘要：

Brillouin scattering experiments in the layer-type semiconductors GaSe and GaS by the pure-transverse phonon domains have been carried out at room temperature. Weak resonant enhancement and cancellation have been found for both materials in the region of transparency. The non-diagonal elastic constants C12 have also been determined to be 3.77 × 1011 dyn cm-2 (GaSe) and 5.35 × 1011 dyn cm-2 (GaS) by measuring the sound velocities of the phonon domains. © 1979.
