| Abstract | We combine in situ electrical transport and Seebeck coefficient measurements with the ionic liquid gating technique to investigate superconductivity and the normal state of FeySe1-xTex (FST) films. We find that the pristine FST films feature a non-Fermi-liquid temperature dependence of the Seebeck coefficient, i.e., S/T similar to AS ln T, and AS is strongly correlated with the superconducting transition temperature (Tc). Ionic liquid gating significantly raises Tc of FST films, for which the Seebeck coefficient displays a different scaling behavior and retains the logarithmic temperature dependence. Moreover, a quantitative relationship between the slope of T-linear resistivity (A rho) and Tc for gated films is observed, i.e., (A rho)1/2 similar to Tc, consistent with previous reports on cuprates and FeSe. The scaling behaviors of AS and A rho point to a spin-fluctuation-associated transport mechanism in gated FeySe1-xTex superconductors. |
