This book was released on 2010 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas and oxide adsorption and their impact on the properties of semiconductor interfaces were investigated at the atomic level with both experimental and theoretical techniques. Two types of semiconductors were studied, an organic semiconductor, employed in chemical field effect transistors (chemFETs) and alternative channel materials for metal oxide field effect transistors (MOSFETs). Adsorption of nitric oxide (NO) on iron phthalocyanine (FePc), an organic semiconductor, was explored to determine the adsorption mechanism of NO. King and Wells sticking measurements were performed on ordered monolayer, multilayer FePc and quasi-amorphous tetra-t-butyl FePc multilayer thin films to determine the impact of surface order and thickness on adsorption. Density functional theory (DFT) results show there is a deep chemisorption well at the metal center. The metal centers are a small fraction of the surface (3%), but the initial sticking probability was 40% at low surface temperature and low incident beam energy. Both the experimental and theoretical data supports molecular NO sticking onto FePc via physisorption to the aromatic periphery followed by diffusion to the Fe metal center, a multiple pathway precursor-mediated chemisorption. To understand the chemical dynamics of bonding at the oxide/semiconductor interface, the adsorption of oxygen, nitrogen, and high-[kappa] dielectrics onto alternative high mobility channel materials, Ge and InAs, was investigated to identify passive oxide/semiconductor interfaces via DFT. DFT modeling of experimental results found oxygen exposure on Ge(0 0 1)-(4 x 2) pins the Fermi level near the valence band due to generation of Ge ad-atoms and formation of a suboxide. Similarly, DFT modeling demonstrated that the nitrided Ge(001) surface was pinned due to generation of Ge ad-atoms and formation of a subnitride. For III-V materials, a comparison was made of the geometric and electronic structures of ordered HfO2 and ZrO2 monolayers on InAs(0 0 1)-(4 x 2). DFT calculations showed that both high-k oxides were able to electronically passivate the InAs(0 0 1)-(4 x 2) surface, decreasing density of states at the Fermi level by removal of dangling bonds and strained bonds on the semiconductor substrate. With a greater atomic understanding of the oxide-semiconductor interfaces, the presented results can help guide future device engineering efforts.

Available in PDF, EPUB and Kindle. Book excerpt: Molecular surface science has made enormous progress in the past 30 years. The development can be characterized by a revolution in fundamental knowledge obtained from simple model systems and by an explosion in the number of experimental techniques. The last 10 years has seen an equally rapid development of quantum mechanical modeling of surface processes using Density Functional Theory (DFT). Chemical Bonding at Surfaces and Interfaces focuses on phenomena and concepts rather than on experimental or theoretical techniques. The aim is to provide the common basis for describing the interaction of atoms and molecules with surfaces and this to be used very broadly in science and technology. The book begins with an overview of structural information on surface adsorbates and discusses the structure of a number of important chemisorption systems. Chapter 2 describes in detail the chemical bond between atoms or molecules and a metal surface in the observed surface structures. A detailed description of experimental information on the dynamics of bond-formation and bond-breaking at surfaces make up Chapter 3. Followed by an in-depth analysis of aspects of heterogeneous catalysis based on the d-band model. In Chapter 5 adsorption and chemistry on the enormously important Si and Ge semiconductor surfaces are covered. In the remaining two Chapters the book moves on from solid-gas interfaces and looks at solid-liquid interface processes. In the final chapter an overview is given of the environmentally important chemical processes occurring on mineral and oxide surfaces in contact with water and electrolytes. Gives examples of how modern theoretical DFT techniques can be used to design heterogeneous catalysts This book suits the rapid introduction of methods and concepts from surface science into a broad range of scientific disciplines where the interaction between a solid and the surrounding gas or liquid phase is an essential component Shows how insight into chemical bonding at surfaces can be applied to a range of scientific problems in heterogeneous catalysis, electrochemistry, environmental science and semiconductor processing Provides both the fundamental perspective and an overview of chemical bonding in terms of structure, electronic structure and dynamics of bond rearrangements at surfaces

Download or read book Physics and Chemistry of III V Compound Semiconductor Interfaces written by Carl W. Wilmsen and published by Springer. This book was released on 1985-08 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of the 111-V compound semiconductors to device fabrica tion has grown considerably in the last few years. This process has been stimulated, in part, by the advancement in the understanding of the interface physics and chemistry of the III-V's. The literature on this subject is spread over the last 15 years and appears in many journals and conference proceedings. Understanding this literature requires consider able effort by the seasoned researcher, and even more for those starting out in the field or by engineers and scientists who wish to apply this knowledge to the fabrication of devices. The purpose of this book is to bring together much of the fundamental and practical knowledge on the physics and chemistry of the 111-V compounds with metals and dielectrics. The authors of this book have endeavored to provide concise overviews of these areas with many tahles ancI grarhs whic. h c. omr>are and summarize the literature. In this way, the book serves as both an insightful treatise on III-V interfaces and a handy reference to the literature. The selection of authors was mandated by the desire to include both fundamental and practical approaches, covering device and material aspects of the interfaces. All of the authors are recognized experts on III-V interfaces and each has worked for many years in his subject area. This experience is projected in the breadth of understanding in each chapter.

This book was released on 2014-02-20 with total page 284 pages. 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.
