Book excerpt: Ferroelectricity in Doped Hafnium Oxide: Materials, Properties and Devices covers all aspects relating to the structural and electrical properties of HfO2 and its implementation into semiconductor devices, including a comparison to standard ferroelectric materials. The ferroelectric and field-induced ferroelectric properties of HfO2-based films are considered promising for various applications, including non-volatile memories, negative capacitance field-effect-transistors, energy storage, harvesting, and solid-state cooling. Fundamentals of ferroelectric and piezoelectric properties, HfO2 processes, and the impact of dopants on ferroelectric properties are also extensively discussed in the book, along with phase transition, switching kinetics, epitaxial growth, thickness scaling, and more. Additional chapters consider the modeling of ferroelectric phase transformation, structural characterization, and the differences and similarities between HFO2 and standard ferroelectric materials. Finally, HfO2 based devices are summarized. Explores all aspects of the structural and electrical properties of HfO2, including processes, modelling and implementation into semiconductor devices Considers potential applications including FeCaps, FeFETs, NCFETs, FTJs and more Provides comparison of an emerging ferroelectric material to conventional ferroelectric materials with insights to the problems of downscaling that conventional ferroelectrics face

Download or read book Hafnium written by Hongyu Yu and published by Nova Science Publishers. This book was released on 2014-01-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hafnium is a chemical element with the symbol Hf and atomic number 72. This book brings together contributions from experts in their related fields to illustrate the significance and importance of hafnium in different forms. This book is composed of six chapters written by experts in their respective fields making this book valuable to the group-IV materials science communities. The subjects presented in the book offer a general overview of the important issues of various hafnium compounds (eg: Hafnium nitride/Hafnium carbide application as a coating material, and Hafnium oxide application as the dielectric layer in non-volatile memory/state-of-the-art CMOS devices). We believe the book is of great scientific and educational value for many readers. Readers thus can familiarise themselves with the latest knowledge in the related fields.
Download or read book Hafnium in Nuclear Engineering written by V. D. Risovany and published by . This book was released on 2001 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practical interest in hafnium expressed by nuclear engineers, and the recently increased number of scientific publications on the subject make a systematic work of collected data very important and timely. Along with results already published, this book includes original data obtained by the authors on hafnium radiation and corrosion resistance. Attention was paid to the mail features of hafnium production as well as the subsequent fabrication technologies, since the performance of hafnium components strongly depends on the properties of the original materials.
Download or read book Chemical Methods of Rock Analysis written by D. Hutchison and published by Elsevier. This book was released on 2012-12-02 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: A practical guide to the methods in general use for the complete analysis of silicate rock material and for the determination of all those elements present in major, minor or trace amounts in silicate and other rocks that are routinely, commonly or occasionally determined by methods that are considered to be essentially chemical in character. Such methods include those based upon spectrophotometry, flame emission spectrometry and atomic absorption spectroscopy, as well as gravimetry, titrimetry and the use of ion-selective electrodes. Separation stages are described in full, using precipitation, solvent extraction, distillation, and ion-ex procedures as appropriate. The third edition has been fully revised and updated.
Download or read book Critical Mineral Resources of the United States written by K. J. Schulz and published by Geological Survey. This book was released on 2017 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

The four-membered heterocycles are abundantly present in various natural and synthetic products of pharmacological importance. This chapter describes the natural abundance, synthesis, chemical reactivity, structural features and their medicinal importance. This class of compounds are present as sub-structures in penicillin and cytotoxic Taxol. Lastly, a chapter on the natural abundance, synthesis, chemical reactivity and pharmacological importance of 5-membered heterocycles with N,O,S heteroatom is covered.
