Study of Ionic Conduction and Dielectric Behavior of Pure and K+ Doped Ag2CdI4

چکیده

The ionic conductivity of 8, 9 and 10 mol% K doped Ag2CdI4 showed slight decrease whereas the phase transition was observed almost at the same temperature as it reported for pure Ag2CdI4. This decrease in conductivity likely results from decrease in free volume because of the larger K ions ( K r  = 133 pm and Ag r  = 129 pm) entering Ag2CdI4 lattice which is unchanging in size. The dielectric constant of Ag2CdI4 was found to increase with increasing temperature as the orientation of dipoles is facilitated in rising temperature.

Zirconia doped with low-valent cations (e.g. Y or Ca) exhibits an exceptionally high ionic conductivity, making them ideal candidates for various electrochemical applications including solid oxide fuel cells (SOFC) and oxygen sensors. It is nevertheless important to study the undoped, monoclinic ZrO2 as a model system to construct a comprehensive picture of the electrical behaviour. In pure zir...

Electronic Conduction in Pure and Chromium-doped Rutile at 1273 K

The symmetric chain Pt-TiO -Pt was studied by means of complex impedance spectroscopy at T = 1273 K for pure and chromium-doped rutile in the partial pressure of oxygen range from 10 to 1 atm. The isothermal variations of electronic conductivity of rutile doped with 1 to 5 % atoms Cr as a function of P were interpreted in terms of point defects by the model of mixed-valence chromium. The compar...
