It is shown that the optimal parameters achieved proper choice of geometrical configuration of the TBRTS that determined by the energy of the electromagnetic field. Renormalized parameters of the electronic spectrum (offset and attenuation) at cryogenic and room temperature calculated by the method of Green's functions. Investigated the contributions of different mechanisms of electron-phonon interaction in the renormalization of the electron states in Depending on the configuration of the example RTS enhanced core experimental stage efficiency. It is shown that the contribution of interface phonons several times dominated the contribution of longitudinal phonons.
