Elemental superconductor Sn with a body-centered tetragonal structure, $\\beta$-Sn, exhibits superconductivity below the superconducting transition temperature ($T_{\\rm c}=3.72$ K) at ambient pressure. $T_{\\rm c}$ of Sn increases with lowering dimension such as in thin film and nanowire growth, or by high-pressure application. For thin films, $T_{\\rm c}$ exhibits a slight increase up to approximately 4 K compared to the bulk value, attributable to the crystalline size and lattice disorder.
