摘要

We successfully grew single crystals of Cs2AgFeCl6 double perovskite measuring ~ 12 mm×01 mm using the acid precipitation method. The dielectric relaxation and charge conduction mechanism has been investigated using temperature-dependent impedance spectroscopy correlated with modulus spectroscopy. We observed the temperature-dependent transition relaxation mechanism from non-Debye-type to Debye-type and the negative temperature coefficient of resistance (NTCR)-type characteristics in Cs2AgFeCl6 single crystals. Moreover, a significant change in dielectric properties, loss factor, electric modulus, and conductivity with temperature has been observed. This investigation provides essential insights into dielectric relaxation behaviour. It elucidates the carrier conduction mechanisms in Cs2AgFeCl6 lead-free double perovskite single crystals that will help design a new optoelectronic device class.
