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

Mapping Urban Spaces focuses on medium-sized European cities and more specifically on their open spaces from psychological, sociological, and aesthetic points of view. The chapters illustrate how the characteristics that make life in medium-sized European cities pleasant and sustainable – accessibility, ease of travel, urban sustainability, social inclusiveness – can be traced back to the nature of that space. The chapters develop from a phenomenological study of space to contributions on places and landscapes in the city. Centralities and their meaning are studied, as well as the social space and its complexity. The contributions focus on history and theory as well as concrete research and mapping approaches and the resulting design applications. The case studies come from countries around Europe including Poland, Italy, Greece, Germany, and France, among others. The book will be of interest to students, scholars, and practitioners in architecture, urban planning, and landscape architecture.

This second edition of a successful and highly-accessed monograph has been extended by more than 100 pages. It includes an enlarged coverage of applications for materials characterization and analysis. Also a more detailed description of strategies for determining free energies of ion transfer between miscible liquids is provided. This is now possible with a “third-phase strategy” which the authors explain from theoretical and practical points of view. The book is still the only one detailing strategies for solid state electroanalysis. It also features the specific potential of the techniques to use immobilized particles (for studies of solid materials) and of immobilized droplets of immiscible liquids for the purpose of studying the three-phase electrochemistry of these liquids. This also includes studies of ion transfer between aqueous and immiscible non-aqueous liquids. The bibliography of all published papers in this field of research has been expanded from 318 to now 444references in this second edition. Not only are pertinent references provided at the end of each chapter, but the complete list of the cited literature is also offered as a separate chapter for easy reference.

Immobilizing particles or droplets on electrodes is a novel and most powerful technique for studying the electrochemical reactions of three-phase systems. It gives access to a wealth of information, ranging from quantitative and phase analysis to thermodynamic and kinetic data of electrode processes. Three-phase electrodes with immobilized droplets provide information on the electrochemistry of redox liquids and of compounds dissolved in inert organic liquids. Such measurements allow the determination of the Gibbs energies of the transfer of cations and anions between immiscible solvents, and thus make it possible to assess the hydrophobicity of ions – a property that is of great importance for pharmaceutical applications, biological studies, and for many fields of chemistry.The monograph gives, for the first time, a comprehensive overview of the results published in more than 300 papers over the last 15 years. The experiments are explained in detail, applications from many different fields are presented, and the theoretical basis of the systems is outlined.

Dieses Lehrbuch gibt eine moderne und verständliche Darstellung der chemischen Gleichgewichte in Lösungen. Wegen ihrer Bedeutung werden hauptsächlich wässrige Lösungen behandelt, ohne aber nichtwässrige Systeme zu vernachlässigen. Die Theorie und die daraus abgeleiteten Erkenntnisse für experimentelle Arbeiten bilden einerseits die Grundlage der Analytischen Chemie und sind andererseits für alle Lösungsreaktionen in der Umweltchemie, Biochemie, Geochemie bis hin zur Pharmazie und Medizin von essenzieller Bedeutung. Seit mehreren Jahrzehnten ist dieses Lehrbuch das erste, in welchem die chemischen Gleichgewichte in Lösungen wieder als eigenständiges Lehrgebiet, dem eine grundlegende Bedeutung für die gesamte Chemie zukommt, vorgestellt werden.Das Buch ist für Studierende der Chemie, Biochemie, Pharmazie, Umweltwissenschaften und aller anderen Studiengänge mit Chemie-Modulen geeignet.Für die dritte Auflage wurde das Buch vollständig durchgesehen und um Ausführungen zu biochemischen und umweltchemischen Aspekten ergänzt. Professor Schröder wurde als Koautor gewonnen.
