Impedance Response and Dielectric Relaxation in Liquid-Phase Sintered Zn^sub 2^SnO^sub 4^-SnO^sub 2^ Ceramics

Impedance/admittance and dielectric spectroscopy were used to investigate the effect of temperature on the electrical response of liquid-phase sintered Zn^sub 2^SnO^sub 4^-SnO^sub 2^ ceramics. The measurements were performed over a wide frequency range (100 Hz to 10 MHz) at different temperatures. T...

Summary:Impedance/admittance and dielectric spectroscopy were used to investigate the effect of temperature on the electrical response of liquid-phase sintered Zn^sub 2^SnO^sub 4^-SnO^sub 2^ ceramics. The measurements were performed over a wide frequency range (100 Hz to 10 MHz) at different temperatures. The real and the imaginary part of the complex impedance traced semicircles in the complex plane. The resistance and the capacitance of bulk and grain-boundary regions were determined by modeling the experimental results using several equivalent circuits taking into account bulk deep trap states. Admittance complex diagrams were also determined in order to understand better the conduction mechanisms occurring in the polycrystalline Zn^sub 2^SnO^sub 4^-SnO^sub 2^ system. [PUBLICATION ABSTRACT]
