Book Description
L'OXYDATION DU SILICIUM MONOCRISTALLIN EST UNE ETAPE IMPORTANTE DE LA TECHNOLOGIE M.O.S. (METAL-OXIDE-SEMICONDUCTOR). LES TEMPERATURES (!000C) ET LES DUREES D'OXYDATION RELATIVEMENT ELEVEES CREENT DES DEFAUTS STRUCTURAUX NOTAMMENT PREJUDICIABLES A TOUTE MINIATURISATION. AFIN DE PALIER A CET INCONVENIENT, L'UTILISATION DE PRESSIONS D'OXYGENE ELEVEES, DU FAIT DE L'ACCROISSEMENT DE LA REACTIVITE, S'AVERAIT UNE VOIE INTERESSANTE POUR ABAISSER LA TEMPERATURE. DES ETUDES D'OXYDATION ONT ETE MENEES EN OXYGENE SEC DANS UN DOMAINE INEXPLORE (14P000 BAR) (600T80C). SUR LA BASE DU MODELE DE DEAL ET GROVE LES CONSTANTES DE VITESSE ONT ETE DEFINIES AINSI QUE LEUR DEPENDANCE VIS-A-VIS DU PARAMETRE PRESSION. LES COUCHES D'OXYDE ELABOREES DANS DE TELLES CONDITIONS ONT ETE CARACTERISEES TANT AU NIVEAU DES PROPRIETES PHYSICO-CHIMIQUES QU'ELECTRIQUES. CES TRAVAUX TOUT EN APPORTANT DES RESULTATS FONDAMENTAUX ORIGINAUX CONSTITUENT UNE OUVERTURE POUR LA MICRO-ELECTRONIQUE DANS LA MESURE OU L'ABAISSEMENT DES TEMPERATURES D'OXYDATION SOUS PRESSION PEUT CONDUIRE A DES APPLICATIONS INDUSTRIELLES

Book Description
Since the late 20th century, graphene-a one-atom-thick planar sheet of sp2-bonded carbon atoms densely packed in a honeycomb crystal lattice-has garnered appreciable attention as a potential next-generation electronic material due to its exceptional properties. These properties include high current density, ballistic transport, chemical inertness,

Book Description
The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Book Description
Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it was impossible to predict how quickly and thoroughly WiFi would penetrate the marketplace. Today, with WiFi-enabled computers almost as common as Ethernet, it makes even more sense to take the next step and network your community using nothing but freely available radio spectrum. This book has showed many people how to make their network available, even from the park bench, how to extend high-speed Internet access into the many areas not served by DSL and cable providers, and how to build working communities and a shared though intangible network. All that's required to create an access point for high-speed Internet connection is a gateway or base station. Once that is set up, any computer with a wireless card can log onto the network and share its resources. Rob Flickenger built such a network in northern California, and continues to participate in network-building efforts. His nuts-and-bolts guide covers: Selecting the appropriate equipment Finding antenna sites, and building and installing antennas Protecting your network from inappropriate access New network monitoring tools and techniques (new) Regulations affecting wireless deployment (new) IP network administration, including DNS and IP Tunneling (new) His expertise, as well as his sense of humor and enthusiasm for the topic, makes Building Wireless Community Networks a very useful and readable book for anyone interested in wireless connectivity.
