The temperature dependence of piezoelectric, pyroelectric, and dielectric properties have been measured for 001 and 111 oriented 0.92Pb Zn1/3Nb2/3 O3–0.08PbTiO3 PZN-8%PT and 0.955Pb Zn1/3Nb2/3 O3–0.045PbTiO3 PZN-4.5%PT single crystals poled by two different poling methods, i.e., room temperature RT poling and poling through field cooling FC . Compared with the RT poling case, some interesting f...

We report the structure and magnetic properties of Zn1–xMnxO thin fi lms grown on Si(001) substrates by pulsed laser deposition. Structure and phase evolution with Mn doping has been studied using x-ray diffraction, electron diffraction, and high-resolution electron microscopy. The undoped and 1% Mn-doped ZnO fi lms are completely (001) oriented, and further Mn doping deteriorates the (001) ori...

The effect of Be concentration on the formation of CdSe self-assembled quantum dots grown on Zn1−xBexSe by molecular-beam epitaxy has been investigated using photoluminescence, atomic force microscopy, contactless electroreflectance, and surface photovoltage spectroscopy. Systematic decrease of the quantum dot sQDd size by increasing the Be concentration sxd in the Zn1−xBexSe barrier layer has ...

Novel chitosan-zinc copper oxide (Zn1-xCuxO) composites were electrochemically synthesized through galvanostatic deposition. The prepared chitosan-based composite thin films were elaborately investigated to determine their structural, morphological, compositional, impedance, and corrosion properties. X-ray diffraction analysis was performed to reveal their structural orientation of composite th...

The title compound, [Zn(2)(CHO(2))(C(8)H(3)O(5))(C(3)H(7)NO)(2)](n), is a three-dimensional metal-organic framework, of which two independent Zn(II) atoms (denoted Zn1 and Zn2) are linked by both 4-oxidoisophthalate and formate bridging ligands. The 4-oxidoisophthalate ligands link two Zn1-type and three Zn2-type atoms, forming a corrugated sheet roughly parallel to the ac plane. The formate io...
