Origin of soft-mode stiffening and reduced dielectric response in SrTiO3 thin films
The problem of the reduced dielectric response in thin films of high-permittivity materials is analyzed by studying the soft-mode response in several SrTiO3 thin films by means of Fourier transform far infrared, monochromatic submillimeter, and micro-Raman spectroscopies. A 300-nm-thick metalorganic chemical vapor deposition film, quasiepitaxially grown on a ~0001! sapphire substrate with a per...
متن کاملDielectric relaxor and ferroelectric relaxor: Bi-doped paraelectric SrTiO3
In this article, we report the evolution of the dielectric behavior from a dielectric relaxor to a ferroelectric relaxor with variation of Bi concentration in (Sr121.5xBix)TiO3 (0<x<0.2). In the doping range 0.0005<x<0.002, two dielectric modes A and B are induced. The temperature (Tm) where the permittivity maximum occurs for modes A and B is independent of Bi concentration and of dc electric ...
متن کاملDielectric response of temperature-graded ferroelectric films
The dielectric susceptibility and dielectric tunability of the temperature-graded BaTiO3 thin films are investigated by using a modified transverse Ising model, taking the four-spin interaction and quantum fluctuation into account. There is a broad and smooth peak of the dielectric susceptibility at low temperature except for the sharp dielectric peak corresponding to the phase-transition tempe...
متن کاملElectric-field-induced soft-mode hardening in SrTiO3 films
We have studied electric-field-induced Raman scattering in SrTiO3 thin films using an indium-tin-oxide/SrTiO3/SrRuO3 structure grown by pulsed laser deposition. The soft mode polarized along the field becomes Raman active. Experimental data for electric-field-induced hardening of the soft modes and the tuning of the static dielectric constant are in agreement described by the Lyddane-Sachs-Tell...
متن کاملMolecular dynamics study of dielectric response in a relaxor ferroelectric.
We use atomistic molecular dynamics simulations to study relaxor behavior in the 0.75 PbMg(1/3)Nb(2/3)O(3)-0.25 PbTiO(3) material. Even for a fairly small simulation size of 1000 atoms, the system exhibits frequency dispersion and deviation from the Curie-Weiss law typical of relaxor materials. Analysis of the time autocorrelation functions for individual atoms allows us to identify the Nb atom...
