Contribution of interband effects caused by long-wavelength transverse optical phonons to electron-phonon coupling in doped polar insulators
Aleksandr Pishtshev
We estimate the contribution of the long-wavelength el-TO-ph interaction and discuss the effect it has on electron pairing in doped polar systems like SrTiO3 and PbTe. The analytic…
Analytic and geometric properties of photoinduced effects in noncentrosymmetric crystals: photovoltaic current and optical rectification
A. Pishtshev, N. Kristoffel
An original dispersion relation between the stationary coherent nonlinear optical responses by current and polarisation is obtained. The dispersion relation provides a new complime…
Evaluation of the electron-TO-phonon interaction in polar crystals from experimental data
Aleksandr Pishtshev
The aim of this study was to determine the strengths of the coupling of electrons with the polar long-wavelength transverse optical (TO) vibrations from infrared spectroscopy data.…
Long wavelength properties of electron-TO-phonon interactions in polar crystals
Aleksandr Pishtshev
Theoretical analysis dealing with the interaction of electrons with the polar long-wavelength transverse optical (TO) vibrations is presented. The theory is based on the model of a…
