Temperature dependence of electrical properties and crystal structure of 0.29Pb([In.sub.1/2][Nb.sub.1/2])[O.sub.3]-0.44Pb([Mg.sub.1/3][Nb.sub.2/3])[O.sub.3]-0.27PbTi[O.sub.3] single crystalsQian LiYun LiuAndrew Studer
(0.79 − x)Pb(In1/2Nb1/2)O3–0.21Pb(Zn1/3Nb2/3)O3–xPbTiO3 (x = 0.23–0.35) ternary ferroelectric system in the form of ceramics have been synthesized. Its structure and properties have been studied by X-ray powder diffraction and electric measurements. A morphotropic phase boundary ...
while no PS has ever been observed. However, in the present PZ thin films, we observed few domains (see Fig.S9) but a widespread phase separation phenomenon in the form of nanosized intergrowth stripes in PZ/STO thin films.
full-cell EE over 16% can be maintained for over 100 h with a suppressed competitive reaction of H2evolution (FEH2 < 5%) (Fig.3gand Supplementary Figs.39,40). TEM and XPS analysis on the post-reaction catalysts reveal that the Pb-Cu catalyst retains its structure after a long-pe...
The pure Bi2Te3 sample synthesized in this work exhibits n-type conduction. We demonstrate that by small doping of Pb at Bi site a transition in electrical transport form n- to p-type is observed. The figure-of-merit (ZT) of n-type Bi2Te3 is ~0.47 and optimized Bi1.95Pb0.05Te3 ...

1. A method of forming a dielectric thin film on a substrate, said method comprising: combining lead and the constituents of barium and/or strontium titanate in a common solution; calcining said common solution to form the constituents of barium and/or strontium lead titanate; depositing said ...
Full size image Frontier molecular orbitals In order to understand the electronic interaction between the neutral heavy metal adsorbants and graphene quantum dots, we plot in Fig. 4 the frontier molecular orbitals for the C54H18 GQDs after the adsorption of neutral heavy metal adatoms. It is cle...
Their stability, their structural and electrical conductivity properties have been investigated. Sr or Ba for Ca substitution in Bi0.75Ca0.125Pb0.125O1.374 allows the preservation of the β1 high temperature form, by air quenching, within the limits 0.2 ≤ Sr(Sr + Ca)≤ 0.8 and 0.1 Ba(Ba +...
