Organic Electronic Materials

This book brings together selected contributions both on the fundamental information on the physics and chemistry of these materials, new physical ideas and decisive experiments. It constitutes both an insightful treatise and a handy reference for specialists and graduate students working in solid state physics and chemistry, material science and related fields.

Think like an electron Organic electronic materials have many applications and potential in low-cost electronics such as electronic barcodes and in light emitting devices, due to their easily tailored properties. While the chemical aspects and characterization have been widely studied, characterization of the electrical properties has been neglected, and classic textbook modeling has been applied. This is most striking in the analysis of thin-film transistors (TFTs) using thick “bulk” transistor (MOS-FET) descriptions. At first glance the TFTs appear to behave as regular MOS-FETs. However, upon closer examination it is clear that TFTs are unique and merit their own model. Understanding and interpreting measurements of organic devices, which are often seen as black-box measurements, is critical to developing better devices and this, therefore, has to be done with care. Electrical Characterization of Organic Electronic Materials and Devices Gives new insights into the electronic properties and measurement techniques for low-mobility electronic devices Characterizes the thin-film transistor using its own model Links the phenomena seen in different device structures and different measurement techniques Presents clearly both how to perform electrical measurements of organic and low-mobility materials and how to extract important information from these measurements Provides a much-needed theoretical foundation for organic electronics

In the near future, organic semiconductors may be used in a variety of products, including flat-screen TVs, e-book readers, and third-generation organic photovoltaics applications, to name just a few. While organic electronics has received increased attention in scientific journals, those working in this burgeoning field require more in-depth coverage of the subject. Considering the rapid development in this field, Organic Electronics: Materials, Processing, Devices and Applications is a long-overdue assessment of state-of-the-art technology in organic electronics. This valuable reference harnesses the insight of various experts in the field, who contribute entire chapters on their area of specialty, covering chemistry and materials, fundamental physics, device processing, fabrication, and applications. Coverage includes cutting-edge advances in: Organic vapor phase deposition to fabricate organic nanostructures Organic semiconductor device physics Organic thin film and vertical transistors Organic photovoltaic cells OLED technologies for flat panel displays and lighting With its detailed discussion of the latest developments in the field of organic semiconductor materials and devices, this versatile book is ideally suited as a reference tool for scientists, engineers, and researchers or as an overview for those new to the field. In either capacity, its broad range of material will serve as a base for the further development of new sciences and technologies in this area.

Dear Readers, Since the ground-breaking, Nobel-prize crowned work of Heeger, MacDiarmid, and Shirakawa on molecularly doped polymers and polymers with an alternating bonding structure at the end of the 1970s, the academic and industrial research on hydrocarbon-based semiconducting materials and devices has made encouraging progress. The strengths of semiconducting polymers are currently mainly unfolding in cheap and easily assembled thin ?lm transistors, light emitting diodes, and organic solar cells. The use of so-called “plastic chips” ranges from lightweight, portable devices over large-area applications to gadgets demanding a degree of mechanical ?exibility, which would overstress conventionaldevices based on inorganic,perfect crystals. The ?eld of organic electronics has evolved quite dynamically during the last few years; thus consumer electronics based on molecular semiconductors has gained suf?cient market attractiveness to be launched by the major manufacturers in the recent past. Nonetheless, the numerous challenges related to organic device physics and the physics of ordered and disordered molecular solids are still the subjects of a cont- uing lively debate. The future of organic microelectronics will unavoidably lead to new devi- physical insights and hence to novel compounds and device architectures of - hanced complexity. Thus, the early evolution of predictive models and precise, computationally effective simulation tools for computer-aided analysis and design of promising device prototypes will be of crucial importance.

Organic flexible electronics represent a highly promising technology that will provide increased functionality and the potential to meet future challenges of scalability, flexibility, low power consumption, light weight, and reduced cost. They will find new applications because they can be used with curved surfaces and incorporated in to a number of products that could not support traditional electronics. The book covers device physics, processing and manufacturing technologies, circuits and packaging, metrology and diagnostic tools, architectures, and systems engineering. Part one covers the production, properties and characterisation of flexible organic materials and part two looks at applications for flexible organic devices. Reviews the properties and production of various flexible organic materials. Describes the integration technologies of flexible organic electronics and their manufacturing methods. Looks at the application of flexible organic materials in smart integrated systems and circuits, chemical sensors, microfluidic devices, organic non-volatile memory devices, and printed batteries and other power storage devices.

Edited and written by the leading researchers and engineers from such companies as Philips, 3M, Xerox, Infineon, PlasticLogic, Eastman Kodak, Dupont, AIXTRON, and Hueck Folien, this book presents unrivalled and undiluted expertise from those who know best how to assess the risks, opportunities and where this technology is really heading. As such, this practical approach complements the more scientific and fundamentals-oriented literature on the market by providing readers with a first-hand insight into industrial activities to commercialize organic electronics. Following an introduction to the topic, including the history, motivation, benefits and potentials, it reviews recent advances and covers all three important facets of organic electronics: the chemical compounds and materials, manufacturing techniques, and the resulting devices together with their current applications.
