Figure 5. Impedance spectroscopy measurements of SDC films with different strain.

Figure 5

(a) Conductivity measurement of the MgO+BZO+STO (MgO-BS) template platform compared with literature references of unstrained Sm-doped ceria bulk: 20 at.% Sm (20SDC(1) (ref. 39)) and 10 and 20 at.% Sm (10SDC(2) and 20SDC(2) (ref. 40)). (b) Comparison of conductivity measurements of the SDC films fabricated for this study with different in-plane tensile strain values. (c) Activation energy for ion migration as a function of tensile strain. The error bar is determined form the standard deviation of the fit and empirically by comparison of independent measurements. (d) Activation energy versus SDC thickness and (e) Arrhenius pre-exponential factor of the SDC films with different strain values.
