摘要：
Structural features due to an anharmonicity of GaAs optical vibrations have been observed on the temperature dependence of the optical vibrational modes localized in GaAs layers. The Gruneisen parameters of localized optical vibrations far from the center of the Brillouin zone have been determined experimentally for the first time.
