Effects of doping, cation stoichiometry, and the processing conditions on the dielectric properties of high-K CaCu₃Ti₄O₁₂ ceramics

Creator:

Kwon, Seunghwa

Abstract:

Since its discovery, the anomalous dielectric behavior of CaCu₃Ti₄O₁₂ (CCTO) has drawn a great deal of attention for many possible applications in electronic devices. The origin of the giant dielectric constant in CCTO was explained via an internal barrier layer capacitor model, and it has been reported that the dielectric...

Defect Mechanisms in Bismuth-based Perovskites

Creator:

Kumar, Nitish

Abstract:

The aim of this research is to develop a fundamental understanding of the dominant defect species and the relevant defect equilibrium conditions for bismuth-containing perovskites to help guide the development of these materials for emerging applications. This is of paramount importance for many demanding applications, because ultimately the defect equilibria...
