Abstract:
1. A composition of matter for a layered ionic superconductor comprising a plurality of layers of atomic elements and comprising: a) a first kind of layer comprising a plurality of ions of the atomic element cesium; b) a second kind of layer comprising a plurality of ions of the atomic element fluorine; c) a third kind of layer comprising a plurality of ions of the atomic elements sodium and oxygen; and d) a fourth kind of layer comprising a plurality of ions of the atomic elements bismuth and oxygen; wherein: the first kind of layer being adjacent to the second kind of layer and adjacent to the third kind of layer, the second kind of layer being adjacent to the fourth kind of layer, and the composition of matter having about 2 parts sodium, about 2 parts cesium, about 1 part bismuth, about 2 parts fluorine, and about 3 parts oxygen, whereby the composition provides a superconductor having a substantially improved superconducting transition temperature.
