In two-dimensional (2D) superconducting films, the transition temperature $T_\\text{c}$ at which resistance vanishes, $R_\\Box(T_\\text{BKT}){=}0$, is set by the Berezinskii-Kosterlitz-Thouless (BKT) mechanism and satisfies $T_\\text{BKT}< T_{c0}$, where $T_{c0}$ is the mean-field transition temperature.
