Book Description
L'objectif de ce travail est la fabrication de transistors organiques transparents aux longueurs d'onde optiques sur un substrat organique transparent pour des applications ophtalmiques. Après une présentation générale des propriétés électriques et électroniques des matériaux utilisés une étude plus spécifique est dédiée au pentacène. Ce semi-conducteur parmi les plus performant est implémenté lors de la phase expérimentale de ce travail Une recherche bibliographique a été menée sur les transistors à base de pentacène et sur la modélisation des transistors organiques dont le fonctionnement en régime d'accumulation est nécessaire si des courants de fonctionnement significatifs sont recherchés. Dans la partie expérimentale de ce travail, des transistors sont réalisés. La nécessité de mise en œuvre de procédés basses températures est alors mise en évidence. Dans ces conditions des transistors entièrement organiques présentant des mobilités de 6.10-3 cm2.V-1 .s-1 sont obtenus.

Book Description
Ellipsometry is the method of choice to determine the properties of surfaces and thin films. It provides comprehensive and sensitive characterization in contactless and non-invasive measurements. This book gives a state-of-the-art survey of ellipsometric investigations of organic films and surfaces, from laboratory to synchrotron applications, with a special focus on in-situ use in processing environments and at solid-liquid interfaces. In conjunction with the development of functional organic, meta- and hybrid materials for new optical, electronic, sensing and biotechnological devices and fabrication advances, the ellipsometric analysis of their optical and material properties has progressed rapidly in the recent years.

Book Description
Recognition receptors play a key role in the successful implementation of chemical and biosensors. Molecular recognition refers to non-covalent speci?c binding between molecules, one of which is typically a macromolecule or a molecular assembly, and the other is the target molecule (ligand or analyte). Biomolecular recognition is typically driven by many weak interactions such as hydrogen bo- ing, metal coordination, hydrophobic forces, van der Waals forces, pi-pi interactions and electrostatic interaction (due to permanent charges, dipoles, and quadrupoles) the polarization of charge distributions by the interaction partner leading to ind- tion and dispersion forces, and Pauli-exclusion-principle-derived inter-atomic repulsion, and a strong, “attractive” force arising largely from the entropy of the solvent and termed the hydrophobic effect. In recent years, there has been much progress in understanding the forces that drive the formation of such complexes, and how these forces are relate to the physical properties of the interacting molecules and their environment allows rational design of molecules and materials that interact in speci?c and desired ways. This book presents a signi?cant and up-to-date review of the various recognition elements, their immobilization, characterization techniques by a panel of dist- guished scientists. This work is a comprehensive approach to the recognition receptors area presenting a thorough knowledge of the subject and an effective integration of these receptors on sensor surfaces in order to appropriately convey the state-of the-art fundamentals and applications of the most innovative approaches.

Book Description
Architecture and Modern Literature explores the representation and interpretation of architectural space in modern literature from the early nineteenth century to the present, with the aim of showing how literary production and architectural construction are related as cultural forms in the historical context of modernity. In addressing this subject, it also examines the larger questions of the relation between literature and architecture and the extent to which these two arts define one another in the social and philosophical contexts of modernity. Architecture and Modern Literature will serve as a foundational introduction to the emerging interdisciplinary study of architecture and literature. David Spurr addresses a broad range of material, including literary, critical, and philosophical works in English, French, and German, and proposes a new historical and theoretical overview of this area, in which modern forms of "meaning" in architecture and literature are related to the discourses of being, dwelling, and homelessness.

Book Description
Silicon, as a single-crystal semiconductor, has sparked a revolution in the field of electronics and touched nearly every field of science and technology. Though available abundantly as silica and in various other forms in nature, silicon is difficult to separate from its chemical compounds because of its reactivity. As a solid, silicon is chemically inert and stable, but growing it as a single crystal creates many technological challenges. Crystal Growth and Evaluation of Silicon for VLSI and ULSI is one of the first books to cover the systematic growth of silicon single crystals and the complete evaluation of silicon, from sand to useful wafers for device fabrication. Written for engineers and researchers working in semiconductor fabrication industries, this practical text: Describes different techniques used to grow silicon single crystals Explains how grown single-crystal ingots become a complete silicon wafer for integrated-circuit fabrication Reviews different methods to evaluate silicon wafers to determine suitability for device applications Analyzes silicon wafers in terms of resistivity and impurity concentration mapping Examines the effect of intentional and unintentional impurities Explores the defects found in regular silicon-crystal lattice Discusses silicon wafer preparation for VLSI and ULSI processing Crystal Growth and Evaluation of Silicon for VLSI and ULSI is an essential reference for different approaches to the selection of the basic silicon-containing compound, separation of silicon as metallurgical-grade pure silicon, subsequent purification, single-crystal growth, and defects and evaluation of the deviations within the grown crystals.

Book Description
Transparent conducting materials are key elements in a wide variety of current technologies including flat panel displays, photovoltaics, organic, low-e windows and electrochromics. The needs for new and improved materials is pressing, because the existing materials do not have the performance levels to meet the ever- increasing demand, and because some of the current materials used may not be viable in the future. In addition, the field of transparent conductors has gone through dramatic changes in the last 5-7 years with new materials being identified, new applications and new people in the field. “Handbook of Transparent Conductors” presents transparent conductors in a historical perspective, provides current applications as well as insights into the future of the devices. It is a comprehensive reference, and represents the most current resource on the subject.
