| 描述 | The dynamical properties of solids have recently attracted renewed interest in connection with the increasing understanding of phase transitions and re- lated phenomena. In particular, soft modes or, more generally, phonon ‘a(chǎn)nom- alies‘ seem to play an important role in structural and electronic phase tran- sitions, such as ferroelectric or superconducting transitions. The understanding of the mechanisms responsible for the occurrence of unusually low frequencies in phonon spectra requires a detailed analysis of the microscopic forces governing the lattice vibrations. Of particular importance is the influence of the electron- lattice interaction in the adiabatic approximation which in many cases is the origin of peculiarities in the phonon self-energy. In this work the vibrational spectra of pure non-metals and of those con- taining point defects are investigated. ‘ In these materials the interrelation be- tween the pseudo-harmonic forces (determining the phonon dispersion re- lations) and the non-linear anharmonic and electron-phonon forces (as they act in infrared and Raman spectra) is most obvious and can be quantitatively analysed in terms of appropriate models. The main task i |
