Candidate ferroelectrics via ab initio high-throughput screening of polar materials

open access: yesnpj Computational Materials
Ferroelectrics are a class of polar and switchable functional materials with diverse applications, from microelectronics to energy conversion. Computational searches for new ferroelectric materials have been constrained by accurate prediction of the ...

Ferroelectricity in Silver Perovskite Oxides [PDF]

open access: yesarXiv, 2011
There are two silver perovskite oxides: AgNbO3 and AgTaO3. AgNbO3 has a noncentrosymmetric group of Pmc21 at room temperature with a ferri-electric ordering of polarization. Such a ferri-electric state with small polarization can be changed into a ferroelectric state with very large polarization by a high electric field or by a chemical modification ...

A Thermodynamic Theory of Proximity Ferroelectricity [PDF]

open access: yesarXiv
Proximity ferroelectricity has recently been reported as a new design paradigm for inducing ferroelectricity, where a non-ferroelectric polar material becomes a ferroelectric by interfacing with a thin ferroelectric layer. Strongly polar materials, such as AlN and ZnO, which were previously unswitchable with an external field below their dielectric ...

The retunable SHF-range signal delay line based on ferroelectrics and diamond films [PDF]

open access: yesTekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2010
The article describes the principles of creation of a broadband miniature SHF-range signal delay line based on ferroelectrics and diamond films. The parameters of obtained ferroelectrics and diamond films have been given. The possible design of the delay
