This book presents materials fundamentals of novel gate dielectrics that are being introduced into semiconductor manufacturing to ensure the continuous scalling of the CMOS devices. This is a very fast evolving field of research so we choose to focus on the basic understanding of the structure, thermodunamics, and electronic properties of these materials that determine their performance in device applications. Most of these materials are transition metal oxides. Ironically, the d-orbitals responsible for the high dielectric constant cause sever integration difficulties thus intrinsically limiting high-k dielectrics. Though new in the electronics industry many of these materials are wel known in the field of ceramics, and we describe this unique connection. The complexity of the structure-property relations in TM oxides makes the use of the state of the art first-principles calculations necessary. Several chapters give a detailed description of the modern theory of polarization, and heterojunction band discontinuity within the framework of the density functional theory. Experimental methods include oxide melt solution calorimetry and differential scanning calorimetry, Raman scattering and other optical characterization techniques, transmission electron microscopy, and x-ray photoelectron spectroscopy. Many of the problems encounterd in the world of CMOS are also relvant for other semiconductors such as GaAs. A comprehensive review of recent developments in this field is thus also given. The book should be of interest to those actively engaged in the gate dielectric research, and to graduate students in Materials Science, Materials Physics, Materials Chemistry, and Electrical Engineering.

This monograph offers a comprehensive overview of diverse quantization phenomena in layered materials, covering current mainstream experimental and theoretical research studies, and presenting essential properties of layered materials along with a wealth of figures. This book illustrates commonly used synthesis methods of these 2D materials and compares the calculated results and experimental measurements, including novel features not yet reported. The book also discusses experimental measurements of magnetic quantization, theoretical modeling for studying systems and covers diversified magneto-electronic properties, magneto-optical selection rules, unusual quantum Hall conductivities, and single- and many-particle magneto-Coulomb excitations. Rich and unique behaviors are clearly revealed in few-layer graphene systems with distinct stacking configuration, stacking-modulated structures, silicon-doped lattices, bilayer silicene/germanene systems with the bottom-top and bottom-bottom buckling structures, monolayer and bilayer phosphorene systems, and quantum topological insulators. The generalized tight-binding model, the static and dynamic Kubo formulas, and the random-phase approximation are developed/modified to thoroughly explore the fundamental properties and propose the concise physical pictures. Different high-resolution experimental measurements are discussed in detail, and they are consistent with the theoretical predictions. Aimed at readers working in materials science, physics, and engineering this book should be useful for potential applications in energy storage, electronic devices, and optoelectronic devices.

The effect of introducing a multilayer microstructure on the dielectric properties of polymer materials is evaluated in 32- and 256-layer films with alternating polycarbonate PC and polyvinylidene-hexafluoropropylene (coPVDF) layers. The permittivity, dielectric loss, dielectric strength, and energy density were measured as a function of the relative PC/coPVDF volume concentrations. The permittivity follows an effective medium model while the dielectric strength was typically higher than that predicted by a volume fraction based weighted average of the components. Energy densities as high as ~14 J /cm3, about 60% greater than that of the component polymers, are measured for 50% PC/50% coPVDF films.

Van der Waals Ferroelectrics A comprehensive guide to a unique class of compounds with a variety of applications Since the discovery of graphene, there has been intensive interest in two-dimensional materials with similar electronic and industrial applications. The limitations on the usefulness of graphene itself, however, have powered the search for other materials with similar properties. One such class of materials, the phosphorous chalcogenides, has proven a particularly fruitful avenue for research, due to the favorable band gap and ferroelectric properties of these materials. Van der Waals Ferroelectrics provides, for the first time, a detailed overview of this highly relevant and sought-after class of materials, also known as transition metal chalcogenophosphates (TMCPs). Focusing on physical properties, the book explores the complex physics underlying these compounds as well as the unique characteristics that have driven their ever-increasing importance to the materials science community. Van der Waals Ferroelectrics readers will also find: Both computational and experimental perspectives on TCMP compounds In-depth discussion of the properties essential to the design and construction of devices like sensors, actuators, memory chips, and capacitors The first detailed review of the functional properties of TCMP compounds, such as ferrielectricity, electrostriction, and ionic conductivity Van der Waals Ferroelectrics is a useful reference for materials scientists, inorganic chemists, solid state chemists, solid state physicists, electrical engineers, and libraries supporting these professions.

Layered crystals, characterized by a quasi-two-dimensional character of certain physical properties, play an interesting role in surface science. First of all they provide excellent inert substrates for epitaxial deposition and physisorption studies. The surfaces of layered crystals, however, are interesting in their own right because they make a relevant class of low-dimensional phenomena accessible to surface probes. Change density waves, incommensurate structures, phonon anomalies and high Tc superconductivity are well known examples. This book collects a series of review articles written by outstanding specialists on the structural assessment and spectroscopy of layered structures with surface-sensitive probes such as scanning microscopy and helium atom scattering, the theoretical analysis of their electronic and vibrational surface states, and the investigation of physisorbed overlayers.

Surfaces and Interfaces of Solid Materials emphasises both experimental and theoretical aspects of surface and interface physics. Beside the techniques of preparing well-defined solid surfaces and interfaces basic models for the description of structural, vibronic and electronic properties of interfaces are described, as well as fundamental aspects of adsorption and layer growth. Because of its importance for modern microelectronics special emphasis is placed on the electronic properties of semiconductor interfaces and heterostructures. Experimental topics covering the basics of ultrahigh-vacuum technology, electron optics, surface spectroscopies and electrical interface characterization techniques are presented in the form of separate panels.
