Abstract: Abstract The temperature and dc bias stability of the dielectric constant and loss tangent of CaCu3Ti4O12 samples sintered under different oxygen atmospheres are discussed. The results suggest that the metal-oxygen vacancy related defects not only… read more here.

Abstract: Abstract In the present work, a giant dielectric constant (e′) ∼ 11672 was developed in a CaCu3Ti4.15Zr0.05O12 ceramic with a very low loss tangent (tanδ) ∼ 0.011 at 30 °C and 1 kHz over a temperature range of −60 °C to 110 °C. The resulting… read more here.
