Charge transfer in the high dielectric constant materials CaCu3Ti4O12 and CdCu3Ti4O12

C. C. Homes, T. Vogt, S. M. Shapiro +3

The cubic perovskite-related ceramic CaCu3Ti4O12 has a very high static dielectric constant ~10000 at room temperature (RT), which drops to about 100 below about 100 K. Substitutin…
