The orientation dependence of the longitudinal piezoelectric coefficient, d(33)(*), is investigated as a function of temperature in BaTiO3 and PbTiO3 crystals using the Landau-Ginsburg-Devonshire theory. We show that a presence of the ferroelectric-ferroel ...
This article reviews recent advances in the studies of the piezoelectric properties of perovskite materials. Perovskite compositions are the best known and the largest family of ferroelectric and piezoelectric materials.: The dependence of the longitudinal ...
A new method to measure the diffusion of adsorbed molecules over macroscopic distance on single crystal surfaces is presented and demonstrated with the system CO on Pt(111). A controlled coverage of molecules, typically of the order of 0.01 monolayer, is d ...
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 ...
The extracellular interferon gamma receptor alpha-chain (IFN gamma R) is believed to comprise two discrete approximately 110 amino acid immunoglobulin-like domains, perhaps similar to those seen in the crystal structure of the extracellular human growth ho ...
The hollandite high-pressure polymorph of plagioclase has been identified in shock-induced melt veins of the Sixiangkou 16 chondrite. It is intimately intergrown with feldspathic glass within grains previously thought to be "maskelynite." The crystallograp ...
This thesis is concerned with the theoretical study of the physical characteristics of metallic surfaces. Ab initio quantum calculations are performed to determine the electronic properties of clean elemental metal surfaces, fully accounting for the materi ...
Using recently published experimental data we calculated the piezoelectric response of rhombohedral 0.67Pb(Mg1/3Nb2/3)O-3-0.33PbTiO(3) monodomain single crystals along arbitrary directions. The calculations indicate that the value of the longitudinal piezo ...
The longitudinal d(33) piezoelectric coefficient was studied in rhombohedral Pb(Zr0.6Ti0.4)O-3 thin films with (111), (100), and "random" orientation. The largest d(33) was found in (100)-oriented films and the smallest along the polarization direction in ...
The authors have investigated the transmission properties and defect characteristics of layer-by-layer metallic photonic crystals. Thay have demonstrated experimentally that the metallicity gap of these crystals extends to an upper band-edge frequency, and ...
