    Effects of Homogeneous Doping on Electron–Phonon Coupling in SrTiO<sub>3</sub> by Minwoo Park, Suk Bum Chung

    Published 2025-01-01
    “…However, recent experimental reports have set the pairing gap to the critical temperature (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>T</mi><mi>c</mi></msub></semantics></math></inline-formula>) ratio at the BCS value for superconductivity in Nb-doped STO, even though the adiabaticity condition the BCS pairing requires is satisfied over the entire superconducting dome only by the lowest branch of optical phonons. In spite of the strong implications these reports have on specifying the pairing glue, they have not proved sufficient in explaining the magnitude of the optimal doping. …”
