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 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...
متن کاملTemperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures
Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...
متن کاملSynthesis and Properties of Lead Magnesium Niobate Zirconate
Two materials were prepared with composition PbMg0.3Nb0.6Zr0.1O3 (PMNZ/10) and PbMg0.32Nb0.65Zr0.03O3 (PMNZ/3). Slight modifications in lead oxide content of these materials were made to study its influence on the sintering properties. The stoichiometric PMNZ/3 gave the best results. It has a sintering temperature as low as 900°C and a relative dielectric constant of 10 000 at room temperature.
متن کاملPeriodic poling of magnesium-oxide-doped lithium niobate
In this article, poling characteristics and periodic poling of magnesium-oxide-doped lithium niobate ~MgLN! are described. Periodic poling was done by the electric field method, with which uniform gratings were produced. The domain wall velocity as a function of poling field was measured and used to determine conditions for self-terminating periodic poling. A computational model for the self-te...
