We present the results of our calculation of the effects of dynamical coupling of a charge carrier to the electronic polarization and the field-induced lattice displacements at the gate interface of an organic field-effect transistor (OFET). We find that t ...
The capability of switching the spontaneous polarisation under an applied electric field in ferroelectric materials can be exploited for the use in low power, non-volatile, re-writable memory devices. Currently available commercially is ferroelectric rando ...
The paper describes processing and dielectric properties of 0.65Pb(Mn1/3Nb2/3)O-3-0.35PbTiO(3) films deposited on alumina and silicon substrates by screen-printing. Ink development and problems associated with adhesion of electrodes to substrate are discus ...
We develop a theory for investigating atomic-scale dielectric permittivity profiles across interfaces between insulators. A local susceptibility chi(x;omega) is introduced to describe variations of the dielectric response over length scales of the order of ...
Ferroelectric thin films are widely studied nowadays as potential replacements for semiconductors in modern tunable microwave devices such as tunable filters, phase-shifters, frequency mixers, power dividers, etc. Recent progress in the deposition of compl ...
We study the electronic structure and the dielectric permittivity of ultrathin oxide layers on Si(I 00) substrates. By considering two different Si(l 00)-SiO2 interface models, we first show that the electronic structure in the interfacial oxide differs fr ...
The preparation and dielectric properties of potassium niobate tantalate (KTN) have been investigated with the aim of exploring the material's potential for ferroelectric tunable applications. The samples were prepared both by conventional sintering in air ...
Pb(Zr-x,Ti1-x)O-3 thin films of homogeneous composition were synthesized by means of a modified sol-gel route on Pt(111)/TiOx/SiO2/Si substrates. The usually observed gradient in B-site composition could be reduced from +/- 12 to +/- 12.5 at% amplitude in ...
Hysteretic and nonlinear dielectric behaviour in ferroelectric ceramics has been of interest since 1950s, when these materials found application in various electronic devices. Presently, these phenomena concern with important areas of science, technology a ...
A theoretical study on the effect of spontaneous polarization screening on the dielectric response of ferroelectric films with 180 degrees domains going through the film thickness (through-domains) is presented. It has been shown by several researchers tha ...
