Abstract
Disclosed herein are embodiments of n and p-type components with high temperature refractory material having a perovskite crystal structure. The material may be doped to generate, for example, p-type and n-type sensor legs. In some embodiments, expensive materials may be avoided. Further, the disclosed materials can avoid high temperature reaction between n-type components and p-type components.
