Switching Characteristics and High-Temperature Dielectric Relaxation Behaviours of Pb(Zn(1/3)Nb(2/3))(0.91)Ti(0.09)O(3) Single Crystal
This work evaluated the resistance switching characteristics in the (100)-oriented Pb(Zn(1/3)Nb(2/3))(0.91)Ti(0.09)O(3) (PZNT) single crystal. The current hysteresis can be closely related to the ferroelectric polarization and we provided a possible explanation using a model about oxygen vacancies t...

description | This work evaluated the resistance switching characteristics in the (100)-oriented Pb(Zn(1/3)Nb(2/3))(0.91)Ti(0.09)O(3) (PZNT) single crystal. The current hysteresis can be closely related to the ferroelectric polarization and we provided a possible explanation using a model about oxygen vacancies to analyze the mechanism of switching. The obvious frequency dispersion of the relative permittivity signified the relaxer-type behavior of the sample. The value of the relaxation parameter γ = 1.48 was estimated from the linear fit of the modified Curie-Weiss law, indicating the relaxer nature. High-temperature dielectric relaxation behaviors were revealed in the temperature region of 400–650 °C. In addition, under the measuring frequency of 10 kHz, ε(r) was tunable by changing the electric field and the largest tunability of ε(r) reached 14.78%. At room temperature, the high pyroelectric coefficient and detectivity figure of merit were reported. |
