Thermoelectric phenomena in layered conductors under the Lifshitz electron topological transition

Theoretically studied the response of the electron system on the non-uniform heating of layered conductors with a quasi-two-electron energy spectrum of arbitrary form under the Lifshitz electron topological transition.when by the of external influences on the conductor, such as pressure, there is a changing surface Fermi (FS) connectivity. For example, the various laws of the dispersion of charge carriers shown a wide variety of electronic topological transitions in layered conductors, which are accompanied by pecular dependence of the kinetic coefficients on magnetic field. At very small distance between cavities (sheets) FS electron movement from one sheet FS to another by magnetic breakdown and yours path become complicated and confusing. In this case calculated the dependence of thermoelectric coefficient on the value and orientation of the strong magnetic field when cyclotron frequency of charge carriers ωc is much higher than the frequency of yours collisions 1/τ Experimental investigations of there phenomena make it possible optain the important information about the electron energy spectrum.
