| 1 | Obtaining,structure,microstructure and dielectric characteristics of ceramics and thin films of ferro-piezoelectric materials based on the PZT system显示文摘This paper presents the results of studies of the structure,microstructure,dependences of the piezoelectric properties on the electric field(dielectric hysteresis loops,reversible nonlinearity,deformation characteristics)and dielectric properties of the ceramic material PCR-13(based on the PZT system)in the temperature range 300-900K and frequencies of an alternating electric field(25÷2·10^(6))Hz.The character of the obtained dependences made it possible to attribute PCR-13 to ferro-hard materials.Using the HF cathodic sputtering method,PCR-13 thin films were fabricated on Si(001)substrates.It is shown that they are polycrystalline textured,while in comparison with bulk material,the film contains tensile stresses of the unit cell in the plane of the substrate and compresses in the perpendicular direction with the valueε_(33)=-0.018.The capacitance-voltage characteristics of the Al/PCR-13/Si/Al heterostructure were studied.The reasons for the revealed patterns are discussed. | Inna Andryushina Anatoliy Pavlenko Sergey Zinchenko Konstantin Andryushin Lidiya Shilkina Ekaterina Glazunova Alexandr Nagaenko Daniil Stryukov Hizir Sadykov Larisa Reznichenko | 2020 | Journal of Advanced Dielectrics2020，10，1： | 0 |
| 2 | The influence of thermodynamic history and external influences on the electrophysical properties of ferropiezoceramic materials based on a multicomponent system PZT-PMN-PZN+SiO_(2)显示文摘This paper presents the results of a comprehensive study of the industrially produced ferro-piezoelectric ceramic material based on the PbZrO_(3)-PbTiO_(3)-PbMn_(1/3)Nb_(2/3)O_(3)-PbZn_(1/3)Nb_(2/3)O_(3)+SiO_(2)system.Studies have confirmed that this material refers to ferrorigid materials with high coercive fields,stable dielectric properties in a wide temperature range,practically no Curie temperature hysteresis,as well as low controllability of the dielectric constant and deformation characteristics by constant bias electric fields.The revealed correlation between dielectric,deformation characteristics and dielectric hysteresis allows us to consider this material as promising for devices operating in power modes:piezotransformers,highly loaded ultrasonic devices,piezoelectric motors,etc. | Konstantin Andryushin Inna Andryushina Hizir Sadykov Alexandr Nagaenko Larisa Reznichenko | 2020 | Journal of Advanced Dielectrics2020，10，1： | 0 |
