Download or read book Theory of Transport Properties of Semiconductor Nanostructures written by Eckehard Schöll and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in the fabrication of semiconductors have created almost un limited possibilities to design structures on a nanometre scale with extraordinary electronic and optoelectronic properties. The theoretical understanding of elec trical transport in such nanostructures is of utmost importance for future device applications. This represents a challenging issue of today's basic research since it requires advanced theoretical techniques to cope with the quantum limit of charge transport, ultrafast carrier dynamics and strongly nonlinear high-field ef fects. This book, which appears in the electronic materials series, presents an over view of the theoretical background and recent developments in the theory of electrical transport in semiconductor nanostructures. It contains 11 chapters which are written by experts in their fields. Starting with a tutorial introduction to the subject in Chapter 1, it proceeds to present different approaches to transport theory. The semiclassical Boltzmann transport equation is in the centre of the next three chapters. Hydrodynamic moment equations (Chapter 2), Monte Carlo techniques (Chapter 3) and the cellular au tomaton approach (Chapter 4) are introduced and illustrated with applications to nanometre structures and device simulation. A full quantum-transport theory covering the Kubo formalism and nonequilibrium Green's functions (Chapter 5) as well as the density matrix theory (Chapter 6) is then presented.

Available in PDF, EPUB and Kindle. Book excerpt: The advent of semiconductor structures whose characteristic dimensions are smaller than the mean free path of carriers has led to the development of novel devices, and advances in theoretical understanding of mesoscopic systems or nanostructures. This book has been thoroughly revised and provides a much-needed update on the very latest experimental research into mesoscopic devices and develops a detailed theoretical framework for understanding their behaviour. Beginning with the key observable phenomena in nanostructures, the authors describe quantum confined systems, transmission in nanostructures, quantum dots, and single electron phenomena. Separate chapters are devoted to interference in diffusive transport, temperature decay of fluctuations, and non-equilibrium transport and nanodevices. Throughout the book, the authors interweave experimental results with the appropriate theoretical formalism. The book will be of great interest to graduate students taking courses in mesoscopic physics or nanoelectronics, and researchers working on semiconductor nanostructures.

Available in PDF, EPUB and Kindle. Book excerpt: Depuis l'introduction du circuit intégré à la fin des années 1950, le nombre de transistors par " puce " n'a cessé de croître, quadruplant approximativement tous les trois ans. Dans ce contexte, la réalisation de composants basés sur une molécule unique, un îlot métallique ou un îlot semiconducteur de dimensions nanométriques (nanostructure) a suscité un intérêt croissant. Les propriétés de transport d'une nanostructure de semiconducteurs sont différentes de celles d'un composant classique (transistor MOSFET) et sont dominées par deux effets. D'une part, le confinement quantique sépare progressivement les niveaux électroniques de l'îlot quand son volume diminue. D'autre part, le rôle joué par les interactions électroniques est d'autant plus important que l'îlot est petit : l'addition d'un électron dans l'îlot modifie significativement son potentiel électrique. Ces " effets à un électron " peuvent être utilisés pour contrôler le passage des porteurs et réaliser toutes sortes de dispositifs innovants, tels que des mémoires et des transistors à un électron. Les nanocristaux de semiconducteurs, qui se présentent grossièrement comme des sphères dont le diamètre est compris entre 2 et 15 nm environ, sont de bons candidats pour la réalisation de dispositifs à un électron fonctionnant à température ambiante. Dans cette perspective, des expériences de spectroscopie tunnel ont été réalisées pour explorer le potentiel et caractériser les propriétés de transport des nanocristaux de semiconducteurs. Les spectres de conductance mesurés sur les nanocristaux avec la pointe d'un microscope à effet tunnel (STM) présentent de nombreux pics liés aux effets du confinement quantique et aux effets à un électron [voir par exemple U. Banin et al., Nature 400, 542 (1999)]. Ces pics ont été attribués aux électrons (trous) qui transitent de la pointe STM dans l'îlot à polarisation positive (négative).

They then describe quantum confined systems, transmission in nanostructures, quantum dots and single electron phenomena. Separate chapters cover interference in diffusive transport and temperature decay of fluctuations, and a chapter on nonequilibrium transport and nanodevices concludes the book. Throughout, Ferry and Goodnick interweave experimental results with the appropriate theoretical formalism. Profusely illustrated, the book will be of great interest to graduate students taking courses in mesoscopic physics or nanoelectronics, as well as to researchers working on semiconductor nanostructures or the development of new ultrasmall devices.

Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Organic lasers are broadly tunable coherent sources, potentially compact, convenient and manufactured at low-costs. Appeared in the mid 60’s as solid-state alternatives for liquid dye lasers, they recently gained a new dimension after the demonstration of organic semiconductor lasers in the 90's. More recently, new perspectives appeared at the nanoscale, with organic polariton and surface plasmon lasers. After a brief reminder to laser physics, a first chapter exposes what makes organic solid-state organic lasers specific. The laser architectures used in organic lasers are then reviewed, with a state-of-the-art review of the performances of devices with regard to output power, threshold, lifetime, beam quality etc. A survey of the recent trends in the field is given, highlighting the latest developments with a special focus on the challenges remaining for achieving direct electrical pumping of organic semiconductor lasers. A last chapter covers the applications of organic solid-state lasers.
