Homebuilt experimental setup used for electrical measurements on nanoscale YDZ films under photon radiation. Sample holder assembly was made of alumina and was installed at the hot zone. The photon radiation source was mounted at the top and continuously air cooled.
Impedance plots of Y70 samples. (a) At with and without UV radiation for two cycles. (b) At with and without green laser radiation.
Arrhenius plot showing temperature dependence of conductivity obtained from ac impedance measurements. In the figure, the open symbols show conductivity in the presence of photo-illumination and the filled symbols show conductivity under normal conditions in air.
Normalized changes in dc conductivity obtained from galvanostatic measurements for YDZ films of two different thicknesses. The changes in single crystal YSZ (sample YSC) is also shown for reference.
Sample list and synthesis method.
