Abstract
A laminated conductor includes a metallic substrate having a surface, a biaxially textured buffer layer supported by the surface of the substrate, the biaxially textured buffer layer comprising LZO and a dopant for mitigating metal diffusion through the LZO, and a biaxially textured conductor layer supported by the biaxially textured buffer layer.
Claims12
A laminated conductor comprising:
- a. a metallic substrate having a surface;
- b. a biaxially textured buffer layer supported by said surface of said substrate, said biaxially textured buffer layer having a pyrochlore crystalline structure and comprising LZO, a first dopant, and a second dopant for mitigating metal diffusion through said LZO, said first dopant comprising at least one element selected from the group consisting of Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, and Ba, and said second dopant comprising at least one element selected from the group consisting of Ca, Mg, Bi, Se, Co, Cr, Mn, Cu, Nb, Ta, Ti, Hf, V, and Si;
- c. a biaxially textured CeO2 capping layer supported by and in contact with said biaxially textured, doped LZO buffer layer;
- and
- d. a biaxially textured conductor layer supported by and in contact with said biaxially textured CeO2 capping layer.
