Nonlinear electrical behaviors and conductivity mechanisms in Ca1-xYbxCeNbWO8 ceramics

Yuanwei Lin et al.

Summary: This study investigates the conductivity mechanisms of Ca1-xYbxCeNbWO8 ceramics prepared by solid-state sintering. It is found that CeO2 and CeNbO4 phases appear with Yb3+ doping, affecting the grain size and Ce3+ concentration in the ceramics. The nonlinear electrical behaviors are attributed to different conductivity mechanisms at high and low temperatures, with variable-range hopping and thermal activation mechanisms observed.
