Figure 5From: Ionic Transport Properties in Nanocrystalline Ce0.8A0.2O2-δ (with A = Eu, Gd, Dy, and Ho) MaterialsPlots of ac conductivity as a function of frequencies at 400°C, in the case of GDC0.2, EuDC0.2, DyDC0.2, and HDC0.2 materials. Inset shows the Arrhenius plots of hopping frequency i.e., log fH versus 1/T in case of GDC0.2 and HDC0.2Back to article page
