Abstract Enhancement of superconducting critical temperature Tc for nano-structured square and rectangular plates is investigated, using the Gor’kov equations and the finite element method. Tc increases with decreasing system size and shows sawtooth behavior as the function of system size. We find the enhancement of Tc becomes larger for narrower rectangular plate. We discuss mechanisms of these behaviors of Tc, investigating quasi-particle eigen-energies and spatial order parameter distributions.
