Аннотация:
The synthesis of the perovskites BiSmO$_3$ was done by the solid-state reaction method. In this communication, the structural and detailed electrical (dielectric, impedance, and conductivity) properties of the material were studied. The X-ray diffraction of BiSmO$_3$ confirmed the conformation of mixed phase perovskites with a cubic crystal structure. The dielectric behavior of the sample is analyzed in a broad frequency range (1 kHz–1 MHz) and temperature range (25.500$^\circ$C). The electrical parameters, like resistance and capacitance of grain and grain boundary of the studied material, were obtained by simulating the experimental impedance data with an equivalent circuit of (CQR) (CR). The calculated optical band gap is 2.4 eV. The NTCR (negative temperature coefficient of resistance) behavior of the ceramic is analyzed from dielectric and impedance studies.
Ключевые слова:
