We report on the ab-plane optical reflectance of an iodine-intercalated Bi1.9Pb0.1Sr2CaCu2O8+delta single crystal in the 80-40000 cm(-1) (10 meV-5 eV) frequency range and at temperatures between 10 and 300 K. As compared to the iodine-free Bi2Sr2CaCu2O8+de ...
PLZT x/65/35 (x = 4, 8, 10) thin films were prepared by the acetic-acid based chemical solution deposition processing from lead tetraacetate, lanthanum nitrate and zirconium and titanium propoxides. Introducing top layer of PLZT with large PbO excess can p ...
Band-structure (BS) calculations of the density of states (DOS) using the full potential augmented plane waves code WIEN97 were performed on the four single-valence vanadium oxides VO, V2O3, VO2 and V2O5. The DOS are discussed with respect to the distortio ...
The facile synthesis of five reagents (Cs+ and Ph3C+ salts) to introduce weakly coordinating anions (WCAs) Al(ORF)4- (ORF: OC(H)(CF3)2; OC(CF3)3) or lithium bridged {(RFO)2Al(m-ORF)2(m-Li)(m-ORF)2Al(ORF)2}- (Ph3C+ salt, ORF: OC(H)(CF3)2) is presented. All ...
III-V nitrides LEDs were grown on c-plane sapphire substrates by molecular beam epitaxy using NH, as nitrogen precursor and solid sources for group-III elements. LEDs based on GaInN/GaN multiple quantum well structures were fabricated. Their electrolumines ...
The effects of niobium doping on the hysteresis parameters of sol-gel Pb-1.1-x/2(Zr0.53Ti0.47)(1-x)NbxO3 (0 < x < 0.05) have been reported fbr two sets of films with analogous grain size and degree of (111) texture but with different surface microstructure ...
Pb(Zr, Ti)O-3 (PZT) and Pb(Zr, Ti, Nb)O-3 (PNZT) thin films have been deposited on platinized silicon substrates by sputtering followed by a postannealing treatment. The Nb concentration in the films varied between 1 and 7 at. % with increments of 1 at. %. ...
Pb(Mg1/3Nb2/3)O-3 (PMN) alkoxide precursor solutions were synthesized and used to prepare thin layers on TiO2/Pt/TiO2/SiO2/Si substrates by spin coating. Many parameters like homogeneity of the solution and appropriate processing must be controlled to mini ...
Pb(Mg1/3Nb2/3)O-3 (PMN) alkoxide precursor solutions were synthesized and used to prepare thin films by spin coating on TiO2/Pt/TiO2/SiO2/Si substrates. Many parameters like the use of homogeneous and stable precursor solutions and appropriate processing w ...
The synthesis and molecular structure of a Pb-Mg bimetallic acetatoalkoxide (Pb-6,Mg-12( mu-OAc)(6)(mu(2), eta(2)-OAc)(18)(mu(3), eta(2)-OC2H4OPr1)(12), space group R-3, a = b = 30.032(2), c = 18.855(2) Angstrom, alpha = beta = 90degrees, gamma = 120degree ...
