Download or read book Integration of Functional Oxides Onto Silicon Substrates written by Hanu K. Arava. This book was released on 2014. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to investigate the integration of functional oxides onto silicon substrates using MBE and Spin-Coating techniques. Functionality is defined, by Materials Department of Imperial College of London, as any property in a material that is not load-bearing in nature. Examples of functionalities that are not load-bearing include magnetic, electric, electro-optic, pyroelectric and many more unique types of behavior. More-than-Moore is the primary motivation within the thesis. Unlike the standard Moore's Law predicting the doubling of semiconductor devices onto a single microchip, More-than-Moore looks into increasing functionality in a single microchip.

Book Synopsis Integration of Functional Oxides with Semiconductors by : Alexander A. Demkov

Download or read book Integration of Functional Oxides with Semiconductors written by Alexander A. Demkov. This book was released on 2014-02-20. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the basic physical principles of the oxide/semiconductor epitaxy and offers a view of the current state of the field. It shows how this technology enables large-scale integration of oxide electronic and photonic devices and describes possible hybrid semiconductor/oxide systems. The book incorporates both theoretical and experimental advances to explore the heteroepitaxy of tuned functional oxides and semiconductors to identify material, device and characterization challenges and to present the incredible potential in the realization of multifunctional devices and monolithic integration of materials and devices. Intended for a multidisciplined audience, Integration of Functional Oxides with Semiconductors describes processing techniques that enable atomic-level control of stoichiometry and structure and reviews characterization techniques for films, interfaces and device performance parameters. Fundamental challenges involved in joining covalent and ionic systems, chemical interactions at interfaces, multi-element materials that are sensitive to atomic-level compositional and structural changes are discussed in the context of the latest literature. Magnetic, ferroelectric and piezoelectric materials and the coupling between them will also be discussed. GaN, SiC, Si, GaAs and Ge semiconductors are covered within the context of optimizing next-generation device performance for monolithic device processing.

Book Synopsis Epitaxy of Crystalline Oxides for Functional Materials Integration on Silicon by : Gang Niu

Download or read book Epitaxy of Crystalline Oxides for Functional Materials Integration on Silicon written by Gang Niu. This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: Oxides form a class of material which covers almost all the spectra of functionalities : dielectricity, semiconductivity, metallicity superconductivity, non-linear optics, acoustics, piezoelectricity, ferroelectricity, ferromagnetism...In this thesis, crystalline oxides have beenintegrated on the workhorse of the semiconductor industry, the silicon, by Molecular Beam Epitaxy (MBE).The first great interest of the epitaxial growth of crystalline oxides on silicon consists in the application of "high-k" dielectric for future sub-22nm CMOS technology. Gadoliniumoxide was explored in detail as a promising candidate of the alternative of SiO2. The pseudomorphic epitaxial growth of Gd2O3 on Si (111) was realized by identifying the optimal growth conditions. The Gd2O3 films show good dielectric properties and particularly an EOTof 0.73nm with a leakage current consistent with the requirements of ITRS for the sub-22nmnodes. In addition, the dielectric behavior of Gd2O3 thin films was further improved by performing PDA treatments. The second research interest on crystalline oxide/Si platform results from its potential application for the "More than Moore" and "Heterogeneous integration" technologies. TheSrTiO3/Si (001) was intensively studied as a paradigm of the integration of oxides on semiconductors. The crystallinity, interface and surface qualities and relaxation process of the STO films on silicon grown at the optimal conditions were investigated and analyzed. Several optimized growth processes were carried out and compared. Finally a "substrate-like" STO thin film was obtained on the silicon substrate with good crystallinity and atomic flat surface. Based on the Gd2O3/Si and SrTiO3/Si templates, diverse functionalities were integrated on the silicon substrate, such as ferro-(piezo-)electricity (BaTiO3, PZT and PMN-PT),ferromagnetism (LSMO) and optoelectronics (Ge). These functional materials epitaxially grown on Si can be widely used for storage memories, lasers and solar cells, etc.

Book Synopsis Advanced Ceramic Materials by : Ashutosh Tiwari

Download or read book Advanced Ceramic Materials written by Ashutosh Tiwari. This book was released on 2016-08-05. Available in PDF, EPUB and Kindle. Book excerpt: Ceramic materials are inorganic and non-metallic porcelains, tiles, enamels, cements, glasses and refractory bricks. Today, "ceramics" has gained a wider meaning as a new generation of materials influence on our lives; electronics, computers, communications, aerospace and other industries rely on a number of their uses. In general, advanced ceramic materials include electro-ceramics, optoelectronic-ceramics, superconductive ceramics and the more recent development of piezoelectric and dielectric ceramics. They can be considered for their features including mechanical properties, decorative textures, environmental uses, energy applications, as well as their usage in bio-ceramics, composites, functionally graded materials, intelligent ceramics and so on. Advanced Ceramic Materials brings together a group of subject matter experts who describe innovative methodologies and strategies adopted in the research and development of the advanced ceramic materials. The book is written for readers from diverse backgrounds across chemistry, physics, materials science and engineering, medical science, pharmacy, environmental technology, biotechnology, and biomedical engineering. It offers a comprehensive view of cutting-edge research on ceramic materials and technologies. Divided into 3 parts concerning design, composites and functionality, the topics discussed include: Chemical strategies of epitaxial oxide ceramics nanomaterials Biphasic, triphasic and multiphasic calcium orthophosphates Microwave assisted processing of advanced ceramic composites Continuous fiber reinforced ceramic matrix composites Yytria and magnesia doped alumina ceramic Oxidation induced crack healing SWCNTs vs MWCNTs reinforcement agents Organic and inorganic wastes in clay brick production Functional tantalum oxides Application of silver tin research on hydroxyapatite
