20. This is similar to the quantum-size oscillations of the critical temperature reported in our previous papers (see, e.g., Ref.): width-dependent oscillations of the critical temperature accompanied by pronounced size-dependent resonant enhancements are smoothed in real nanowires into an overall enhancement with decreasing nanowire cross section.
