Polar phonons in some compressively stressed epitaxial and polycrystalline SrTiO3 thin films
D. Nuzhnyy, J. Petzelt, S. Kamba +5
Several SrTiO3 (STO) thin films without electrodes processed by pulsed laser deposition, of thicknesses down to 40 nm, were studied using infrared transmission and reflection spect…
Pressure on charged domain walls and additional imprint mechanism in ferroelectrics
P. Mokry, A. K. Tagantsev, J. Fousek
The impact of free charges on the local pressure on a charged ferroelectric domain wall produced by an electric field has been analyzed. A general formula for the local pressure on…
Anharmonicity of BaTiO_3 single crystals
Y. L. Wang, A. K. Tagantsev, D. Damjanovic +3
By analyzing the dielectric non-linearity with the Landau thermodynamic expansion, we find a simple and direct way to assess the importance of the eighth order term. Following this…
Comments on "A model for fatigue in ferroelectric perovskite thin films" published in Appl. Phys. Lett, 76, 1060 (2000); addendum, ibid. p.3655
Alexander K. Tagantsev
The paper comments on a paper by Dawber and Scott published in Appl. Phys. Lett, 76,1060 (2000) and addendum (ibid. p.3655), which addresses an important issue of the physics of fe…
The Broad Brillouin Doublet and CP of Ktao_3 : Second Sound vs. Two-Phonon Difference Scattering
E. Farhi, A. K. Tagantsev, B. Hehlen +3
Low-T Brillouin spectra of the incipient ferroelectric KTaO3 exhibit a broad central peak (CP), and additional Brillouin doublets (BD), that can both be related to phonon-density f…
