| Abstract Scope |
Vanadium and Yttrium co-doping strategies for BaTiO3 have been investigated to improve reliability and lifetime of multi-layered ceramic capacitors (MLCC). Miniaturization of electronic devices requires more reliable MLCCs without sacrificing performance. Vanadium and yttrium were explored as co-dopants in BaTiO3 to reduce electronic carriers via Fermi level pinning to improve reliability. The multi-valent state of vanadium presents a greater challenge to understanding the defect structure in the material. Co-doped samples were prepared using a solution doping method and the dense disk samples were characterized using impedance spectroscopy measurements to show the effects of powder processing on the electrical properties of the material. Impedance spectroscopy data will be presented to show bulk and grain boundary resistances, as a function of temperature, to better understand how the dopants may lead to improved electrical degradation resistance. This research was funded by the Air Force Office of Scientific Research under grant FA9550-19-1-0222. |
