A Review on Electronic Transport Properties of Individual Conducting Polymer Nanotubes and Nanowires
During the past 15 years, significant progress has been made in synthesis, structural and electrical characterizations, and applications of conducting polymer nanotubes/wires. In this chapter, a brief review of the recent advances in electronic transport properties of individual conducting polymer nanotubes/wires prepared by both the template-free selfassembly method and the template method is presented. Results with broad interest have been discussed. For example, it was found that the electrical conductivity of the individual polymer tubes/wires increases by several times of magnitudes with decreasing outer diameter (size effect in electrical conductivity). The crossover from Mott to Efros...
Organic Electronics 1
Due to their special properties, organic semiconductors enable the development of large-area, low-cost devices, paving the way for flexible and nomadic applications that advantageously replace those made with traditional semiconductors. This book describes the properties and deposition methods of organic semiconductors, transparent conductive materials or metals which are used in the fabrication of organic devices. The physical processes (optical, electrical and interface) that control the mechanisms in the formation and transport of the charge carriers of the materials are studied and explained in detail. Organic Electronics 1 introduces the fundamental and applied aspects of the field of organic electronics. It is intended for researchers and students in university programs or engineering schools specializing in electronics, energy and materials.
Nanowires
This book describes nanowires fabrication and their potential applications, both as standing alone or complementing carbon nanotubes and polymers. Understanding the design and working principles of nanowires described here, requires a multidisciplinary background of physics, chemistry, materials science, electrical and optoelectronics engineering, bioengineering, etc. This book is organized in eighteen chapters. In the first chapters, some considerations concerning the preparation of metallic and semiconductor nanowires are presented. Then, combinations of nanowires and carbon nanotubes are described and their properties connected with possible applications. After that, some polymer nanowire...
Nanowires
Low-dimensional structures have attracted extensive research interest due to their promising applications in nanotechnology. These low-dimensional materials have the potential to make revolutionary changes in science and technology because a reduction in size not only enables a faster speed and greater computing power but also helps reduce device form factors. As such, this book examines the behaviors of oxide nanowires, group III–V compounds, and other nanowires, including basic Si nanowires, metallic wires, and complex geometrical nanowires.
Fueling Resistance
"This book explores how and why controversies over liquid biofuels (bioethanol and biodiesel) and hydraulic fracturing ("fracking") unfolded in surprisingly similar ways in the global North and South. In the early 2000s, the search was on for fuels that would reduce greenhouse gas emissions, spur economic development in rural regions, and diversify national energy supplies. Biofuels and fracking took centre stage as promising commodities and technologies. But controversy quickly erupted. Global enthusiasm for these fuels, and the widespread projections for their production around the world, collided with local politics. Rural and remote places, such as coastal east Africa and Canada's Yukon ...
Organic Electronics, Volume 2
Due to their special properties, organic semiconductors enable the development of large-area, low-cost devices, paving the way for flexible and nomadic applications that advantageously replace those made with traditional semiconductors. In this second volume, we study the main applications of organic semiconductors, such as organic light-emitting diodes (OLEDs), solar cells (OPVs) and organic field-effect transistors (OFETs). The commercialization of these new devices is then discussed within the Brabec triangle framework, in which yield, stability and production costs are the key factors. We also address the environmental impact of organic devices for their future development. This book presents the application side of organic electronics from a technological, economic and environmental perspective. It is intended for researchers and students in university programs or engineering schools specializing in electronics, energy and materials.
Farming Systems and Food Security in Africa
Knowledge of Africa’s complex farming systems, set in their socio-economic and environmental context, is an essential ingredient to developing effective strategies for improving food and nutrition security. This book systematically and comprehensively describes the characteristics, trends, drivers of change and strategic priorities for each of Africa’s fifteen farming systems and their main subsystems. It shows how a farming systems perspective can be used to identify pathways to household food security and poverty reduction, and how strategic interventions may need to differ from one farming system to another. In the analysis, emphasis is placed on understanding farming systems drivers ...
Introduction à l’électronique organique 1
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. Ce volume décrit les propriétés et les méthodes de dépôt des matières comme les semi-conducteurs organiques, les matériaux transparents conducteurs ou les métaux, qui sont utilisées dans la fabrication des dispositifs organiques. Les processus physiques (optiques, électriques et d’interface) qui régissent et contrôlent les mécanismes d’injection, de formation et de transport des porteurs de charge des matériaux sont étudiés et expliqués en détail. Cet ouvrage introduit les aspects fondamentaux et appliqués du domaine de l’électronique organique. Il s’adresse aux chercheurs et aux étudiants en filières universitaires ou en écoles d’ingénieurs se spécialisant en électronique, énergies et matériaux.

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.
