Abstract

In a zero-dimensional superconductor, quantum size effects1, 2 (QSE) not only set the limit to superconductivity, but are also at the heart of new phenomena such as shell effects, which have been predicted to result in large enhancements of the superconducting energy gap3, 4, 5, 6. Here, we experimentally demonstrate these QSE through measurements on single, isolated Pb and Sn nanoparticles. In ...
