Self-consistent calculation of the autolocalization barrier for quasiparticles in anisotropic crystal
A. Shelkan
Abstract
The energy of the electron wave packet interacting with lattice distortion, is considered in anisotropic crystal. Anisotropy of the electron and phonon spectra as well as of the electron-phonon interaction are taken into account. The height of the barrier between free and self-trapped states is calculated in dependence on the anisotropy parameters. The calculation is done numerically, using continual aproximation. The analytical solution is obtained for some cases of quasi-two and quasi-one-dimensional spectra. Key words: anisotropy; polarons; barrier.
