Extremely Enhanced Nonlinear Current-Voltage Properties of Tb-Doped CaCu3Ti4O12 Ceramics

Nonlinear current–voltage properties of CaCu3Ti4O12 ceramics were extremely enhanced by doping with Tb. Substitution of Tb to CaCu3Ti4O12 resulted in a decrease in grain size due to the ability of Tb ions to inhibit grain boundary mobility. The dielectric properties of CaCu3Ti4O12 ceramics were degr...
