CO molecules in a supersonic molecular beam are resonantly excited from the X 1SIGMA+, upsilon" = 0 ground state to the a 3PI, upsilon' = 0 metastable state using pulsed laser radiation at 206 nm. In the excitation region a static electric field is applied ...
Energy balance and reciprocity relations are studied for harmonic inhomogeneous plane waves that are incident upon a stack of continuous absorbing dielectric media that are macroscopically characterized by their electric and magnetic permittivities and the ...
Dielectric properties of perovskites are studied both to gain insight into fundamental aspects of the freezing of polar disorder, and to investigate their technological potential. The dynamics of freezing of polar disorder is investigated in single crystal ...
Pb(Mg1/3Nb2/3)O-3 thin films were prepared from modified alkoxide solution precursors and their dielectric and electromechanical characteristics were investigated. Preparation of the films is very sensitive to processing parameters. The influence of differ ...
We investigate the accuracy of the weighted-density approximation (WDA) in predicting the dielectric response of materials from first-principles. WDA is a genuinely non-local formulation for the exchange-correlation term of density-functional theory. Still ...
We investigate structural, electronic, dynamical, and dielectric properties of zircon (ZrSiO4) within density-functional theory. The atomic structure is fully relaxed and the structural parameters are found to differ by less than 1.5% from the experimental ...
Pyrochlore free Pb(Mg1/3Nb2/3)O-3 (PMN) thin films were prepared from alkoxide-based solution precursors. The influence of different seeding layers and chemical solution on the microstructures is shown. Dielectric, electrostrictive, and piezoelectric prope ...
Pyrochlore free 0.9Pb(Mg1/3Nb2/3)O-3-0.1PbTiO(3) thin films were prepared from alkoxide-based solution precursors. Preferential (111) crystallographic orientation was obtained on TiO2/Pt/TiO2/SiO2/Si substrates by spin coating. Dielectric, electrostrictive ...
