Available in PDF, EPUB and Kindle. Book excerpt: Discover the materials set to revolutionize the electronics industry The search for electronic materials that can be cheaply solution-processed into films, while simultaneously providing quality device characteristics, represents a major challenge for materials scientists. Continuous semiconducting thin films with large carrier mobilities are particularly desirable for high-speed microelectronic applications, potentially providing new opportunities for the development of low-cost, large-area, flexible computing devices, displays, sensors, and solar cells. To date, the majority of solution-processing research has focused on molecular and polymeric organic films. In contrast, this book reviews recent achievements in the search for solution-processed inorganic semiconductors and other critical electronic components. These components offer the potential for better performance and more robust thermal and mechanical stability than comparable organic-based systems. Solution Processing of Inorganic Materials covers everything from the more traditional fields of sol-gel processing and chemical bath deposition to the cutting-edge use of nanomaterials in thin-film deposition. In particular, the book focuses on materials and techniques that are compatible with high-throughput, low-cost, and low-temperature deposition processes such as spin coating, dip coating, printing, and stamping. Throughout the text, illustrations and examples of applications are provided to help the reader fully appreciate the concepts and opportunities involved in this exciting field. In addition to presenting the state-of-the-art research, the book offers extensive background material. As a result, any researcher involved or interested in electronic device fabrication can turn to this book to become fully versed in the solution-processed inorganic materials that are set to revolutionize the electronics industry.
Download or read book Fabrication of Thin Film Lead Zirconate Titanate Cantilevers for Energy Harvesting Applications written by Wardia Mechtaly Debray and published by . This book was released on 2010 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin films of ferroelectric relaxor solid solutions, Pb(Zr x Ti 1-x )O3 -Pb(Zn1/3 ,Nb2/3 )O3 or PZT-PZN, have been fabricated using the sol-gel process on non-conducting ZrO2 surfaces for energy harvesting applications. The sol-gel process used to fabricate these films is a modification of the inverted mixing order (IMO) process that has been previously developed for PZT.1 The relaxor thin films, also prepared using the sol-gel process, are susceptible to formation of the undesired non-ferroelectric pyrochlore phase.2 We adopted a strategy based on three key parameters to obtain single-phase perovskite thin films. The first is the use of a PbTiO3 (PT) seed layer, which has been shown to be effective for perovskite phase nucleation.3 The second, is the use of excess lead in the starting solution, and the third is the use of a high ramp rate anneal for film crystallization. It is shown that by using these three process parameters one can eliminate the undesired pyrochlore phase. The ability to obtain single phase PZT-PZN perovskite films depends on balancing two competing processes. The first is lead loss during film annealing, which tends to favor nucleation of the pyrochlore phase.4 The second is the nucleation rate of the perovskite phase, which requires the presence of excess lead. The fast-ramp rate anneal increases the perovskite phase nucleation before significant lead is lost from the film. With this scheme we were able to eliminate the pyrocholore phase. The film morphology, as seen in SEM micrographs, shows the benefit of the PT seed layer. Electrical characterization of these films was performed using inter-digitated electrode structures. The results indicate a very strong dependence of the electrical properties on film thickness. The quality of the capacitance "butterfly" loops improved significantly with increasing film thickness. The dielectric constant was extracted from interdigitated electrode structures for three thickness values (270, 540 and 810 nm including a PT layer for nucleation purposes) and was found to be 205, 470 and 803, and the capacitance density per effective area were 167, 470 and 655 pF/mm2 . The reason for the increase in the capacitance is likely due to increasing grain size with film thickness. The coercive voltage for the three thicknesses was found to be ±10V. We used the interdigitated electrode structure in order to operate the cantilever in d33 mode (d33 generates 2 times higher device performance than that of the d31).5

Download or read book Ferroelectric Thin Films written by Carlos Paz de Araujo and published by Taylor & Francis. This book was released on 1996 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for the rapid development of thin film technology, relative to that of bulk materials, is its application to a variety of microelectronic products. Many of the characteristics of thin film ferroelectric materials are utilized in the development of these products - namely, their nonvolatile memory and piezoelectric, pyroelectric, and electro-optic properties. It is befitting, therefore, that the first of a set of three complementary books with the general title Integrated Ferroelectric Devices and Technologies focuses on the synthesis of thin film ferroelectric materials and their basic properties. Because it is a basic introduction to the chemistry, materials science, processing, and physics of the materials from which integrated ferroelectrics are made, newcomers to this field as well as veterans will find this book self-contained and invaluable in acquiring the diverse elements requisite to success in their work in this area. It is directed at electronic engineers and physicists as well as process and system engineers, ceramicists, and chemists involved in the research, design, development, manufacturing, and utilization of thin film ferroelectric materials.

Available in PDF, EPUB and Kindle. Book excerpt: Factors that control phase evolution, microstructural development and ferroelectric domain assemblage are evaluated for chemically prepared lead zirconate titanate (PZT) thin films. Zirconium to titanium stoichiometry is shown to strongly influence microstructure. As Ti content increases, there is an apparent enhancement of the perovskite phase nucleation rate, grain size becomes smaller, and the amount of pyrochlore phase, if present, decreases. While the pyrochlore matrix microstructure for near morphotropic phase boundary composition thin films consists of two interpenetrating nanophases (pyrochlore and an amorphous phase), the pyrochlore microstructure for PZT 20/80 films deposited on MgO substrates is single phase and consists of 10nm grains. Zirconium to titanium stoichiometry also has a substantial influence on process integration. Near morphotropic phase boundary films exhibit extensive reaction with underlying TiO2 diffusion barriers; conversely, there is no chemical reaction for identically processed PZT 20/80 thin films. The authors have attempted to directly correlate the optical quality of PZT thin films to the following microstructural features: (1) presence of a second phase, (2) domain orientation, and (3) nanometer surface morphology.
