Abstract = {{The non Ohmic and giant dielectric properties of CaCu3Ti4O12 and
   Ca0.925Sm0.05Cu3-xZnxTi4O12 (x = 0.0-0.10) ceramics prepared by a
   modified sol-gel method were studied. Influences of (Sm+Zn) co-dopants
   on the crystalline structure and microstructure of CaCu3Ti4O12 ceramics
   were investigated. The lattice parameter value was slightly enhanced,
   while the grain size was greatly reduced by inclusion of (Sm+Zn)
   co-dopants. Interestingly, the dielectric loss tangent in the frequency
   range of 10(2)-10(6) Hz was significantly reduced (tan delta approximate
   to 0.041 at 1 kHz), whereas the dielectric permittivity was still too
   large (> 10(3)). Furthermore, their nonlinear electrical properties were
   significantly enhanced. The nonlinear coefficient and breakdown electric
   field increased with increasing co-dopant concentration. The conduction
   activation energies of the grain and grain boundaries slightly changed,
   while the grain boundary resistance was greatly increased corresponding
   to a reduction in the mean grain size. The variations in giant
   dielectric and nonlinear electrical properties can be well described by
   the internal barrier layer capacitor effect.}},
