Ferroelectric materials for dynamic-memory integrated circuits

A Study of Ferroelectric Properties of the Oscillator Model of PZT-22

“…The typical properties of ferroelectric films are applied in the construction of nonvolatile memory devices (for example, FeRAM), dynamic random access memory, capacitors, infrared receivers, optical processors, waveguide and delaycircuits (delay-lines), appliances of surface-acoustic waves, and various acoustic devices. The physical properties of the films depend on the state (condition) of the surface, stoichiometry, crystalline nature, thickness, microcrystalline nature, crystallographic orientation, and high processing (that is, methods of obtaining films) temperature [1]. The investigation of dielectric properties in millimeter and sub-millimeter spectral range often provides essential information about the dynamic properties of dielectrics [2].…”
