Ferroelectric properties of colemanite

Inorganic Materials, 2006
The electrical conductivity, dielectric permittivity, and loss tangent of colemanite single crystals are measured as functions of temperature, and the fractal scaling law exponent is evaluated. The origin of the colossal dielectric response of hydrogen-bonded crystals is discussed.

Adjustable ferroelectric properties in paraelectric/ferroelectric/paraelectric trilayers

Journal of Physics D: Applied Physics, 2008
A trilayer paraelectric/ferroelectric/paraelectric system is studied within the framework of the Ginzburg–Landau–Devonshire theory in consideration of the elastic interactions between each layer. An analytic expression of the ferroelectric phase transition temperature for the ferroelectric layer is derived.

Low-temperature thermal properties of ferroelectrics

Physical Review B, 1985
Through measurements of the low-temperature thermal conductivity and specific heat, we show that two classes of ferroelectrics can be distinguished. One class exhibits behavior typical of crystalline solids and the other displays behavior identical to that seen in structural glasses.

Excellent Ferroelectric Properties of Hf0.5Zr0.5O2 Thin Films Induced by Al2O3 Dielectric Layer

IEEE Electron Device Letters, 2019
The ferroelectricity of Hf0.5Zr0.5O2 (HZO) thin films has been usually reported to be induced by metallic capping layer. In this work, we successfully obtained ferroelectricity of HZO thin films induced by ultrathin insulating Al2O3 capping layers.

Ferroelectric properties of PbTiO3

Physica, 1962
Abstract A new method for growing single crystals of ferroelectric PbTiO3 is described. A mixture of TiO2, Pb3O4 and KF in the ratio 1 : 2.5 : 6.5 is taken in a platinum crucible and heated to a temperature of about 900°C to 950°C for about 20 hours. The melt is then slowly cooled to room temperature.

Ferroelectric and Pyroelectric Properties of Nano Graded Ferroelectric Films

Advanced Materials Research, 2011
In order to improve the properties of nano graded ferroelectric films (NGFF), the generalized Ginzburg-Landau-Denvonshire (GLD) theory is used to investigate the ferroelectric and pyroelectric properties of NGFF. A function is introduced to describe the local structure of this graded film.
