Abstract
A ternary paraelectric having a Cc structure and a method of manufacturing the same are provided. The ternary paraelectric having a Cc structure includes a material having a chemical formula of A2B4O11 that has a monoclinic system, is a space group No. 9, and has a dielectric constant of 150 to 250, wherein “A” is a Group 1 element, and “B” is a Group 5 element. “A” may include one of Na, K, Li and Rb. “B” may include one of Nb, V, and Ta. The A2B4O11 material may be Na2Nb4O11 in which bandgap energy thereof is greater than that of STO. The A2B4O11 material may have relative density that is greater than 90% or more.
