Enhanced time response and temperature sensing behavior of thermistor using Zn-doped CaTiO3 nanoparticles

  • Subhanarayan Sahoo
Open Access
Research Article


In the present study, Zn-doped CaTiO3 nanocrystalline was synthesized to study the thermistor behavior with temperature. The X-ray powder diffraction analysis showed the formation of a single-phase orthorhombic structure at room temperature. The electrical resistance of the Zn-doped CaTiO3 increased with increasing doping concentration and decreased at higher measuring temperature, showing a negative temperature coefficient of resistance (NTCR) behavior. Different thermistor parameters were calculated using Steinhart–Hart equations, whilst time domain analysis confirmed faster response towards applied voltage.
