On Acoustic Attenuation in Dielectric Solids

Abstract: Starting from the general equation of motion for the atoms of the primitive lattice and using the Green function method the sound absorption coefficient is derived in the threephonon approximation. The here derived results hold for transverse waves in the whole frequency region and for longitudinal ones in the high frequency region ( Q t > 1). The frequency and temperature dependence of the absorption coefficient are discussed for the high and low frequencies (Q t > 1 and 9 t < 1). Using the dispersion relatio… Show more
