Abstract
Official abstract text for this publication.
A capacitor includes a first electrode, a second electrode, and a dielectric. The dielectric is disposed between the first electrode and the second electrode. The dielectric includes a halide and satisfies a requirement 1/2<r<2/3. In this requirement, r is a ratio of the number of cations to the number of anions in the halide included in the dielectric.
