Abstract: Investigations of the electrical conductivity of mixed CuInP2(S xSe1- x)6 crystals were carried out in the frequency range of 20-1 MHz. Anomalies in dc conductivity were observed close to the ferroelectric phase-transition temperature. However, these anomalies are different in selenium- and sulfur-rich compounds. While in the selenium-rich crystals group the anomaly of conductivity is sharp, in the sulfur-rich crystals group it is less expressed. These results indicate that the copper ions contribution to the total conductivity is not vanishing down to the lowest temperatures in sulfur-rich crystals. Moreover, in paraelectric phase the dc conductivity activation energy correlate with the pre-exponential factor according to the Meyer-Neldel law. No conductivity anomaly was observed in mixed CuInP2(S xSe1- x)6 crystals with the dipolar glass or relaxor behavior. [ABSTRACT FROM AUTHOR]
