Abstract
A dielectric of the present disclosure includes an oxide containing hafnium, zirconium, and gallium. In the dielectric, a molar ratio Zr/(Hf+Zr) of a zirconium content to a sum of a hafnium content and the zirconium content is 0.2 or more and less than 1. Further, a molar ratio Ga/(Hf+Zr+Ga) of a gallium content to a sum of the hafnium content, the zirconium content, and the gallium content is more than 0 and less than 0.14.
