The effects of 10 keV Ar+ ion irradiation on the electrical characteristics of BaCe0.9Y0.1O2.95 subject to fluences of 0, 1.0 x 10 exp(17), 5.0 x 10 exp(17) and 1.0 x 10 exp(18) ions/cm2 at room temperature, were investigated using ERDA, SEM, EDX, XPS and AC impedance measurements. The ERDA results...
