The origin of superelectrons lies in the atomic nature. Superelectrons are derived from four special electron pair sets of 1s 2 , 2p 6 , 3d 10 , and 4f 14 , which can be represented as 1 S o of s‐type spin‐singlet pairing in the Russel‐Saunders term symbol. T c increases with the increase of the compressive pressure against these spherical electron clouds by the pinch effect due to excess oxygen in cuprate oxide superconductors and the outermost electrons in the superconducting elements, suggesting the increase of the attractive interaction between electrons.
