"Photodiodes made of small molecular weight organic semiconductors have been fabricated. The organic materials under investigation are p-type Copper phthalocyanine (CuPc) and n-type 3,4,9,10-perylenetetracarboxylic bisbenzimidazole (PTCBI). Current-voltage and capacitance-voltage measurements have been performed to evaluate the electrical properties of the organic photodiodes. Optical measurements including responsivity and temporal response have also been carried out. It has been found that device efficiency of the photodiodes is influenced by the thickness of organic layers as well as the device structures. It is believed that organic layer thickness is a strong function of materials' exciton diffusion lengths. The thickness of the organic layer employed in the fabricated photodiode is 100 A or less. However, the fabricated devices with thin organic layer showed poor performance in terms of saturation current and breakdown voltage. As a result, new device structures have been proposed to overcome the problems. Stacking structure double heterojunction (SDH) and novel comb-like structure single heterojunction (CSH) device configurations have shown a substantial improvement in both electrical and optical parameters. There is at least 3 times enhancement in photocurrent and 10 times increase in external quantum efficiency for photodiodes employing CSH device structure and 100 A organic layer. Improvements in saturation current and breakdown voltage have also been observed. In addition, responsivity measurements in CSH devices have yielded a 7 times improvement. Furthermore, the carrier lifetime of the photodiode is estimated to be around 1 microsecond from the temporal response measurements. The combined effect of thin organic layers and new device structures leads to an overall improvement in device performance." --

Provides first-hand insights into advanced fabrication techniques for solution processable organic electronics materials and devices The field of printable organic electronics has emerged as a technology which plays a major role in materials science research and development. Printable organic electronics soon compete with, and for specific applications can even outpace, conventional semiconductor devices in terms of performance, cost, and versatility. Printing techniques allow for large-scale fabrication of organic electronic components and functional devices for use as wearable electronics, health-care sensors, Internet of Things, monitoring of environment pollution and many others, yet-to-be-conceived applications. The first part of Solution-Processable Components for Organic Electronic Devices covers the synthesis of: soluble conjugated polymers; solution-processable nanoparticles of inorganic semiconductors; high-k nanoparticles by means of controlled radical polymerization; advanced blending techniques yielding novel materials with extraordinary properties. The book also discusses photogeneration of charge carriers in nanostructured bulk heterojunctions and charge carrier transport in multicomponent materials such as composites and nanocomposites as well as photovoltaic devices modelling. The second part of the book is devoted to organic electronic devices, such as field effect transistors, light emitting diodes, photovoltaics, photodiodes and electronic memory devices which can be produced by solution-based methods, including printing and roll-to-roll manufacturing. The book provides in-depth knowledge for experienced researchers and for those entering the field. It comprises 12 chapters focused on: ? novel organic electronics components synthesis and solution-based processing techniques ? advanced analysis of mechanisms governing charge carrier generation and transport in organic semiconductors and devices ? fabrication techniques and characterization methods of organic electronic devices Providing coverage of the state of the art of organic electronics, Solution-Processable Components for Organic Electronic Devices is an excellent book for materials scientists, applied physicists, engineering scientists, and those working in the electronics industry.

In recent years, considerable progress has been made in the study of organic semiconductors. The main directions of investigation, have been determined and substantial results have been achieved in the theoretical treatment of many questions. However, the range of investigations is so broad that it is impossible to discuss all branches fully in a short monograph. In fact, the chemist synthe sizing systems with conjugated bonds and studying their reactivity, the physical chemist studying the catalytic and absorption proper ties of substances with conjugated bonds, the physicist studying the photoelectric and magnetic characteristics of dyes and polynuclear hydrocarbons, and the biologist attempting to explain the mechan ism of energy transfer in the living cell -they are all working in the field of organic semiconductors. Consequentiy, in the present book the authors have not attempted to include all sides of the problem of organic semiconductors. The monograph considers in detail only those questions which appear to the authors to be most immediate and interesting. Other questions are touched on only to the extent necessary to illustrate the main material. The book begins with a statement of material which is of the nature of a review. The main classes of organic semiconductors are mentioned but the methods for their preparation are not illus trated in detail. Somewhat more attention is devoted to the depen dence of the electrical characteristics of organic semiconductors on their structure and chemical composition.

Nanotechnology is a vital new area of research and development addressing the control, modification and fabrication of materials, structures and devices with nanometre precision and the synthesis of such structures into systems of micro- and macroscopic dimensions. Future applications of nanoscale science and technology include motors smaller than the diameter of a human hair and single-celled organisms programmed to fabricate materials with nanometer precision. Miniaturisation has revolutionised the semiconductor industry by making possible inexpensive integrated electronic circuits comprised of devices and wires with sub-micrometer dimensions. These integrated circuits are now ubiquitous, controlling everything from cars to toasters. The next level of miniaturisation, beyond sub-micrometer dimensions into nanoscale dimensions (invisible to the unaided human eye) is a booming area of research and development. This is a very hot area of research with large amounts of venture capital and government funding being invested worldwide, as such Nanoscale Science and Technology has a broad appeal based upon an interdisciplinary approach, covering aspects of physics, chemistry, biology, materials science and electronic engineering. Kelsall et al present a coherent approach to nanoscale sciences, which will be invaluable to graduate level students and researchers and practising engineers and product designers.

The field of organic electronics has seen a steady growth over the last 15 years. At the same time, our scientific understanding of how to achieve optimum device performance has grown, and this book gives an overview of our present-day knowledge of the physics behind organic semiconductor devices. Based on the very successful first edition, the editors have invited top scientists from the US, Japan, and Europe to include the developments from recent years, covering such fundamental issues as: - growth and characterization of thin films of organic semiconductors, - charge transport and photophysical properties of the materials as well as their electronic structure at interfaces, and - analysis and modeling of devices like organic light-emitting diodes or organic lasers. The result is an overview of the field for both readers with basic knowledge and for an application-oriented audience. It thus bridges the gap between textbook knowledge largely based on crystalline molecular solids and those books focusing more on device applications.
