Book Description
Sol-gel processing has been widely used in the preparation of lead zirconate titanate (PZT) thin films. The authors have applied this methodology to the formation of lead magnesium niobate (PMN) spin-cast deposited thin films. Since there is a limited number of soluble, commercially available compounds, the authors have recently synthesized a series of novel metal alkoxides for use as precursors for generation of PMN thin films and powders. The process for generation of the perovskite phase of these PMN powders and films are reported.

Book Description
Nanomaterials via Single-Source Precursors: Synthesis, Processing and Applications presents recent results and overviews of synthesis, processing, characterization and applications of advanced materials for energy, electronics, biomedicine, sensors and aerospace. A variety of processing methods (vapor, liquid and solid-state) are covered, along with materials, including metals, oxides, semiconductor, sulfides, selenides, nitrides, and carbon-based materials. Production of quantum dots, nanoparticles, thin films and composites are described by a collection of international experts. Given the ability to customize the phase, morphology, and properties of target materials, this "rational approach to synthesis and processing is a disruptive technology for electronic, energy, structural and biomedical (nano)materials and devices. The use of single-source chemical precursors for materials processing technology allows for intimate elemental mixing and hence production of complex materials at temperatures well below traditional physical methods and those involving direct combination of elements. The use of lower temperatures enables thin-film deposition on lightweight polymer substrates and reduces damage to complex devices structures such as used in power, electronics and sensors. - Discusses new approaches to synthesis or single-source precursors (SSPs) and the concept of rational design of materials - Includes materials processing of SSPs in the design of new materials and novel devices - Provides comprehensive coverage of the subject (materials science and chemistry) as related to SSPs and the range of potential applications

Book Description
Cu(In, Ga)Se 2 film fabrication by the selenization of the mixed metal/metal-selenide precursors was investigated. For the precursor preparation, the combination of electro deposition, annealing, co-evaporation and pre-selenization methods were employed with sequential sputtering as a control. The precursor structures studied were CuSe/Ga/In, Cu 2-x Se/Ga/In, (Ga, In)-Se/Cu and metallic Cu-Ga/In as a control. Cu 2-x Se/Ga/In precursors were prepared from both electro deposition and co-evaporation. These precursors were selenized in H 2 Se at at 450°C for 5, 15, and 90min. The structures of the precursors and reacted films were examined in terms of the crystalline phases, compositions and morphologies by scanning electron microscopy, energy dispersive spectroscopy, symmetric and asymmetric X-ray diffraction, and Auger electron spectroscopy. The similar selenization reaction rates were obtained for the precursors with copper selenide/Ga/In structures as that for the control precursor while that for the (Ga, In)-Se/Cu seems to be slower than the control. Ga accumulation at the backside of the selenized film was universally observed for the precursors including the control Cu-Ga/In precursor, with the exception of one precursor with the structure of CuSe/Ga/In made from electro deposition. For the CuSe/Ga/In precursor, a hill-like Ga profile with the maximum Ga concentration at the middle of the film was obtained. In addition, increased Ga composition at the front side of the selenized film was obtained for the Cu 2-x Se/Ga/In precursor made from electro deposition compared to the control. The device performance of the solar cells made of these selenized films were also investigated and related to the film properties. The comparable conversion efficiencies were obtained from the three precursors with copper selenide/Ga/In structures as the control. The long wavelength edge of external quantum efficiency curve indicates larger bandgap than the control for the films made from the two precursors including the CuSe/Ga/In and Cu 2-x Se/Ga/In, both started with electron deposition. The enhanced Ga incorporation into Cu(In, Ga)Se 2 structure corresponds to the larger bandgap for these precursors.
