Electron-phonon SAW attenuation in aluminum for all ql
1Dept. of Electr. Comput. and Biomed. Eng., Marquette Univ., Milwaukee, WI.
Abstract:
Theoretical expressions for the electron-phonon contribution to the attenuation of surface acoustic waves (SAW) propagating on a semi-infinite block of material have been obtained for all ql, where q is the sound propagation vector and l is the electron mean-free path. The calculation of the attenuation due to electron-phonon interaction for ql<<1 is straightforward; however, extension of this calculation to all ql values requires knowledge of the ql dependence of the viscous damping coefficients, chi and eta. Approximations for chi and eta for all ql are obtained by analogy with attenuation expressions derived for longitudinal transverse bulk sound waves. Curves for chi, eta, and the electron-phonon contribution to the attenuation of SAW propagating on a semi-infinite block of aluminum are presented.
