Dielectric phase-transition and polarization studies in stepped and compositionally graded lead magnesium niobate–lead titanate relaxor thin films
Ferroelectric properties of chemically heterogeneous multilayers and graded composition thin films of 1−x Pb Mg1/3Nb2/3 O3–xPbTiO3, a well-known relaxor, were prepared using a multitarget pulsed laser ablation system. Target materials with different values of x 0.0, 0.1, 0.2, and 0.3 were used for ablation growth. Films with sharp interfaces and graded interfaces were prepared and were characte...
متن کاملLarge Electrocaloric Effect in Relaxor Ferroelectric and Antiferroelectric Lanthanum Doped Lead Zirconate Titanate Ceramics
Both relaxor ferroelectric and antiferroelectric materials can individually demonstrate large electrocaloric effects (ECE). However, in order to further enhance the ECE it is crucial to find a material system, which can exhibit simultaneously both relaxor ferroelectric and antiferroelectric properties, or easily convert from one into another in terms of the compositional tailoring. Here we repo...
متن کاملFerroelectric Lead Zirconate Titanate and Barium Titanate Nanotubes
Wetting of the pore walls of porous templates is a simple and convenient method to prepare nanotubes. Ferroelectric lead zirconate titanate and barium titanate nanotubes were fabricated by wetting of porous silicon templates of polymeric precursors. The ferroand piezoelectric properties of an individual ferroelectric either of a PZT or a BaTiO3 nanotube were electrically characterized by measur...
متن کاملImpurity-induced ferroelectric relaxor behavior in quantum paraelectric SrTiO3 and ferroelectric BaTiO3
The ‘‘ferroelectric relaxor’’ behavior, which shows a rounded permittivity peak with low-frequency dispersion, was first observed by Smolenskii et al. in the Ba(Ti,Sn)O3 solid solution in 1954. Later, this phenomenon was also observed in Pb(Mg1/3Nb2/3)O3 ~PMN! compounds by the same group. Smolenskii et al. named this phenomenon as a behavior of the ferroelectric with diffuse phase transition ~D...
متن کاملPMN-PT (lead magnesium niobate-lead titanate) piezoelectric material micromachining by excimer laser ablation and dry etching (DRIE)
In the attempt to find the appropriate micromanufacturing technology of PMN-PT (lead magnesium niobate–lead titanate) piezo material, whose MEMS-related applications look promising, two methods are investigated: excimer laser ablation (using KrF gas) and inductively coupled plasma (ICP) dry etching, also known as DRIE (using Ar/C4F8 gases). The paper quantitatively reports the optimal parameter...
