Available in PDF, EPUB and Kindle. 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

Available in PDF, EPUB and Kindle. Book excerpt: Thermodynamics of Certain Refractory Compounds, Volume I: Discussion of Theoretical Studies provides information pertinent to thermodynamics as a significant theoretical tool for predicting the chemical and physical behavior of materials under diverse environmental conditions. This book presents a summary of the methods used to analyze thermodynamic data. Organized into six chapters, this volume begins with an overview of the thermodynamic properties that have been obtained for a selected group of refractory compounds in the range from 0° to 6000°K. This text then examines the class of compounds, including the borides, oxides, carbides, and nitrides of some elements in groups IIA, IIIB, IVB, VB, VIB, VIIB, and VIII as well as some elements from the rare-earth and actinide series. Other chapters consider the need for standardization in methods of obtaining and presenting thermodynamic data. The final chapter deals with the recommendations for the advancement of work. This book is a valuable resource for scientists and engineers.
Download or read book Formation of Ferroelectricity in Hafnium Oxide Based Thin Films written by Tony Schenk and published by BoD – Books on Demand. This book was released on 2017-03-15 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2011, Böscke et al. reported the unexpected discovery of ferroelectric properties in hafnia based thin films, which has since initiated many further studies and revitalized research on the topic of ferroelectric memories. In spite of many efforts, the unveiling of the fundamentals behind this surprising discovery has proven rather challenging. In this work, the originally claimed Pca21 phase is experimentally proven to be the root of the ferroelectric properties and the nature of this ferroelectricity is classified in the frame of existing concepts of ferroelectric materials. Parameters to stabilize this polar phase are examined from a theoretical and fabrication point of view. With these very basic questions addressed, the application relevant electric field cycling behavior is studied. The results of first-order reversal curves, impedance spectroscopy, scanning transmission electron microscopy and piezoresponse force microscopy significantly advance the understanding of structural mechanisms underlying wake-up, fatigue and the novel phenomenon of split-up/merging of transient current peaks. The impact of field cycling behavior on applications like ferroelectric memories is highlighted and routes to optimize it are derived. These findings help to pave the road for a successful commercialization of hafnia based ferroelectrics.
Download or read book Experimental Study of Factors Controlling the Effectiveness of High temperature Protective Coatings for Tungsten written by Jack Brett and published by . This book was released on 1965 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The restrictions imposed by the processes of diffusion, evaporation, and coating substrate reactions on the choice of potential protective coating materials for tungsten were studied analytically and experimentally. The diffusive restriction is the most limiting and eliminates many refractory oxides with otherwise satisfactory attributes. The diffusive properties of rare earth sesquioxides and complex refractory oxides were explored by means of oxidation experiments and a layer growth experiment respectively. Mass spectrometric studies of the vaporization of refractory complex oxides were carried out to determine the applicability of the Wagner-Hauffe method of predicting vaporization rates. Provided certain thermodynamic approximations are valid and the vapor species over the complex oxide are the same as those over the pure component oxides, the predictions yield order of magnitude accuracy. A survey and exploration of reactions of possible coating materials with tungsten was performed emphasizing promising materials from the diffusion studies. (Author).
Download or read book Ultra High Temperature Materials II written by Igor L. Shabalin and published by Springer. This book was released on 2019-04-24 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: This exhaustive work in three volumes and over 1300 pages provides a thorough treatment of ultra-high temperature materials with melting points over 2500 °C. The first volume focuses on Carbon and Refractory Metals, whilst the second and third are dedicated solely to Refractory compounds and the third to Refractory Alloys and Composites respectively. Topics included are physical (crystallographic, thermodynamic, thermo physical, electrical, optical, physico-mechanical, nuclear) and chemical (solid-state diffusion, interaction with chemical elements and compounds, interaction with gases, vapours and aqueous solutions) properties of the individual physico-chemical phases of carbon (graphite/graphene), refractory metals (W, Re, Os, Ta, Mo, Nb, Ir) and compounds (oxides, nitrides, carbides, borides, silicides) with melting points in this range. It will be of interest to researchers, engineers, postgraduate, graduate and undergraduate students alike. The reader is provided with the full qualitative and quantitative assessment for the materials, which could be applied in various engineering devices and environmental conditions at ultra-high temperatures, on the basis of the latest updates in the field of physics, chemistry, materials science and engineering.
