Abstract
It is shown that the assumption that the carriers are small polarons can explain superconductivity in doped or reduced SrTiO2 consistently with the existence of metallic conductivity at very low carrier densities. The attractive polaron-polaron interaction responsible for superconductivity is caused by polaron-intra-valley acoustic phonon interaction, which in this model is only weakly screened by the Coulomb polaron-polaron interaction.Keywords
