| 1 | Fe^(3+)-substitution effect on the thermal variation of J-E characteristics and DC resistivity of quadruple perovskite CaCu_(3)Ti_(4)O_(12)显示文摘The electrical properties of cubic perovskite series,CaCu_(3-x)Ti_(4-x)Fe_(2x)O_(12)with x=0.0,0.1,0.3,0.5,and 0.7,have been studied by employing current density as a function of electric field characteristics registered at different temperatures and thermal variations of direct current electrical resistivity measurements.All of the compositions exhibit strong non-ohmic behavior.The concentration dependence of breakdown field,the temperature at which switching action takes place,and maximum value of current density(J_(max))has been explained on account of structural,microstructural,and positron lifetime parameters.The highest ever reported value of J_(max)=327 mA/cm^(2)has been observed for pristine composition.The values of the nonlinear coefficient advise the suitability of ceramics for low-voltage varistor applications.The Arrhenius plots show typical semiconducting nature.The activation energy values indicate that electric conduction proceeds through electrons with deformation in the system. | Kunal B.Modi Pooja Y.Raval Dolly J.Parekh Shrey K.Modi Niketa P.Joshi Akshay R.Makadiya Nimish H.Vasoya Utpal S.Joshi | 2022 | Journal of Semiconductors2022，43，3： | 0 |
