Book Description
Grâce à leurs propriétés particulières, les semi-conducteurs organiques permettent d’élaborer des dispositifs de grande surface et à coûts réduits, ouvrant la voie aux applications souples et nomades qui remplacent avantageusement celles réalisées avec les semi-conducteurs traditionnels. Dans ce second volume, les principales applications des semi-conducteurs organiques telles que les diodes électroluminescentes (OLED), les cellules solaires (OPV) et les transistors organiques (OFET) sont étudiées. La commercialisation de ces nouveaux dispositifs est ensuite discutée en se basant sur le schéma du triangle de Brabec, dans lequel le rendement, la stabilité et le coût de production sont des facteurs clés. L’impact environnemental des dispositifs organiques est également traité par l’analyse de leur cycle de vie. Cet ouvrage présente les aspects appliqués de l’électronique organique tant sur le plan technologique qu’économique et environnemental. Il s’adresse aux chercheurs et étudiants en filières universitaires ou en écoles d’ingénieurs se spécialisant en électronique, énergies et matériaux.

ISBN: 1119694949
Category : Technology & Engineering
Languages : en
Pages : 304
Book Description
Quantum mechanics is the foundation of modern technology, due to its innumerable applications in physics, chemistry and even biology. This second volume studies Schrödinger's equation and its applications in the study of wells, steps and potential barriers. It examines the properties of orthonormal bases in the space of square-summable wave functions and Dirac notations in the space of states. This book has a special focus on the notions of the linear operators, the Hermitian operators, observables, Hermitian conjugation, commutators and the representation of kets, bras and operators in the space of states. The eigenvalue equation, the characteristic equation and the evolution equation of the mean value of an observable are introduced. The book goes on to investigate the study of conservative systems through the time evolution operator and Ehrenfest's theorem. Finally, this second volume is completed by the introduction of the notions of quantum wire, quantum wells of semiconductor materials and quantum dots in the appendices.
CAD of Circuits and Integrated Systems
Author: Ali MahdoumPublisher: John Wiley & Sons
ISBN: 1786305976
Category : Technology & Engineering
Languages : en
Pages : 288
Book Description
This book addresses the difficulty of obtaining a quality solution, that is, pre optimal or even optimal, in a reasonable time from a central processing unit (CPU). As polynomial problems can be treated by exact methods, the problem posed concerns non-polynomial problems, for which it is necessary to develop efficient algorithms based on heuristics or meta-heuristics. Chapter 3 of this book demonstrates how to develop such algorithms, which are characterized by: an initialization of argued solutions (sometimes, the global optimum can be obtained from such an initialization); a non-random generation of solutions (to avoid generating the same solution several times, or even generating solutions that cannot be achieved); avoidance of being trapped by a local optimum; good use of CPU time by reducing the size of the space of solutions to be explored (which is often very large for such problems) without compromising the quality of the solution; plus a reasoned displacement from one solution to another, to improve the quality of the solution as the processing is carried out. These aspects are applied to concrete applications in the design of integrated circuits and systems at various levels. To do this and to help the reader better understand this problem, Chapters 1 and 2 present basic notions on computational complexity, and the design of integrated circuits and systems.
