Table 1. Characteristics of the single crystal substrates used for this study.

Substrate Crystalline structure Expected epitaxial relation Lattice mismatch (%)
NdGaO3 (110) Orthorhombic perovskite a=5.43 Å c=5.50 Å In-plane SDC(1Inline graphic0)||NGO(1Inline graphic0) SDC(110)||NGO(001) 0.64, 0.39
    Out-of-plane SDC(001)||NGO(110)  
LaAlO3 (001) Pseudocubic perovskite a=3.82 Å In-plane SDC(110)||LAO(100) SDC(1Inline graphic0)||LAO(010) −0.49, −0.49
    Out-of-plane SDC(001)||LAO(001)  
MgO (001) face-centered cubic a=4.21 Å   None ≈−29

Expected epitaxial relations and lattice mismatch with 15 at.% Sm-doped CeO2 are displayed. The lattice mismatch, given in percent, is calculated as (asubstrate – aSDC)/asubstrate.
