Book Description
Discovering scalable routes to fabricate large scale electronic devices on flexible substrates has been the goal of the newly emerging field of flexible macroelectronics. Thin film transistors (TFTs) have been fabricated on flexible substrates by using organic small-molecule and polymer-based materials, or thin layers of crystalline inorganic semiconductors. Recently, films of carbon nanotubes have been proposed as electronic materials with superior electrical performance due to exceptional electrical and mechanical properties of single-walled carbon nanotubes (SWCNTs). In this thesis, some aspects of recent research efforts on integrating arrays of carbon nanotubes into macroelectronic devices are described. Carbon nanotube films have two major uses for flexible macroelectronics. The first approach uses carbon nanotube thin films as active semiconducting materials in the channel of flexible TFTs. Even though, high-performance carbon nanotube thin film transistors have been realized, the electronic non-homogeneity of the as-grown carbon nanotubes in the film limits the device performance for some applications. In this thesis, the application of electrochemical functionalization on carbon nanotube films to improve the electronic homogeneity of the film is described. The effect of the crystal quartz substrates on the growth rate of carbon nanotubes, and whether this can be used to sort out as-grown carbon nanotubes by electronic type is also discussed. Finally, I argue that high density carbon nanotube films can also be used as highly conducting stretchable interconnects on mechanically flexible electronic circuits. The sheet resistance and the nature of the buckling of carbon nanotube films on flexible substrates are discussed.

Book Description
This book describes the use of carbon nanotubes in form of randomly oriented networks in display technology. Carbon nanotubes can behave either like a metal or like a semiconductor and are used in this work as transparent conductive pixel electrodes as well as semiconducting channel in thin-film transistors. Monte-Carlo simulations examine more closely the percolation probabilities of metallic and semiconducting nanotubes. The experimental part covers methods to create stable surfactant suspensions from nanotube powders, simple and cost-effective low temperature deposition processes from liquid phase on glass and flexible plastic substrates and patterning procedures of the created films. Electrical and optical characterization gives insight on their performance. The realization of liquid crystal and OLED displays shows the compatibility of transparent carbon nanotube electrodes with production processes. Results of the semiconductor application are presented on a transistor level. The dependence of the transistor performance on the network density for both, mixed and highly semiconducting nanotubes is discussed.

Book Description
This book presents a comprehensive review of research on applications of carbon nanotubes (CNTs) and graphene to electronic devices. As nanocarbons in general, and CNTs and graphene in particular, are becoming increasingly recognized as the most promising materials for future generations of electronic devices, including transistors, sensors, and interconnects, a knowledge gap still exists between the basic science of nanocarbons and their feasibility for cost-effective product manufacturing. The book highlights some of the issues surrounding this missing link by providing a detailed review of the nanostructure and electronic properties, materials, and device fabrication and of the structure–property–application relationships.

Book Description
With the recently well developed areas of Internet of Thing, consumer wearable gadgets and artificial intelligence, flexible and stretchable electronic devices have spurred great amount of interest from both the global scientific and industrial communities. As an emerging technology, flexible and stretchable electronics requires the scale-span fabrication of devices involving nano-features, microstructures and macroscopic large area manufacturing. The key factor behind covers the organic, inorganic and nano materials that exhibit completely different mechanical and electrical properties, as well as the accurate interfacial control between these components. Based on the fusion of chemistry, physics, biology, materials science and information technology, this review volume will try to offer a timely and comprehensive overview on the flexible and stretchable electronic materials and devices. The book will cover the working principle, materials selection, device fabrication and applications of electronic components of transistors, solar cells, memories, sensors, supercapacitors, circuits and etc.

Book Description
Remarkable progress has been achieved within recent years in developing flexible, wearable, and stretchable (FWS) electronics. These electronics will play an increasingly significant role in the future of electronics and will open new product paradigms that conventional semiconductors are not capable of. This is because flexible electronics will allow us to build flexible circuits and devices on a substrate that can be bent, stretched, or folded without losing functionality. This revolutionary change will impact how we interact with the world around us. Future electronic devices will use flexible electronics as part of ambient intelligence and ubiquitous computing for many different applications such as consumer electronics, medical, healthcare, and security devices. Thus, these devices have the potential to create a huge market all over the world. Flexible, Wearable, and Stretchable Electronics, provide a comprehensive technological review of the state-of-the-art developments in FWS electronics. This book offers the reader a taste of what is possible with FWS electronics and describes how these electronics can provide unique solutions for a wide variety of applications. Furthermore, the book introduces and explains new applications of flexible technology that has opened up the future of FWS electronics.
