This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the nature of charge transport and its limitations on device performance has guided the rational design of organic semiconductors for over a decade. This understanding has led to the development of high performance small molecule and polymeric semiconductors for applications in low-cost complementary logic circuits, displays, lighting, and solar cells. Unfortunately, the large catalog of available materials and processing variables make it difficult to outline general design rules. Specifically, in polycrystalline and semicrystalline organic semiconductors, little is understood about the structural order within a grain and between grains, and even less is known about how this structure affects the material's performance. In this thesis, characterization methods are introduced to address these issues. To understand the structural source of electronic defects, a multi-step Fourier transform X-ray line shape analysis with thorough error analysis is adapted to determine crystallite size and intra-grain cumulative disorder. For the first time, the intra-crystalline disorder in transport-relevant directions is quantitatively determined for a variety of high performing organic semiconductors. These van der Waals bonded crystallites exhibit a wide range of disorder (from

Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, the way human beings interact with technology has been significantly transformed. In our daily life, ever fewer manually controlled devices are used, giving way to automatized houses, cars, and devices. A significant part of this technological revolution relies on signal detection and evaluation, placing detectors as core devices for further technological developments. This book introduces a versatile contribution to achieving light sensing: Organic Semiconductor Devices for Light Detection. The text is organized to guide the reader through the main concepts of light detection, followed by a introduction to the semiconducting properties of organic molecular solids. The sources of non-idealities in organic photodetectors are presented in chapter 5, and a new device concept, which aims to overcome some of the limitation discussed in the previous chapters, is demonstrated. Finally, an overview of the field is given with a selection of open points for future investigation.
Download or read book Charged Semiconductor Defects written by Edmund G. Seebauer and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Defects in semiconductors have been studied for many years, in many cases with a view toward controlling their behaviour through various forms of “defect engineering”. For example, in the bulk, charging significantly affects the total concentration of defects that are available to mediate phenomena such as solid-state diffusion. Surface defects play an important role in mediating surface mass transport during high temperature processing steps such as epitaxial film deposition, diffusional smoothing in reflow, and nanostructure formation in memory device fabrication. “Charged Defects in Semiconductors” details the current state of knowledge regarding the properties of the ionized defects that can affect the behaviour of advanced transistors, photo-active devices, catalysts, and sensors. Features: group IV, III-V, and oxide semiconductors; intrinsic and extrinsic defects; and, point defects, as well as defect pairs, complexes and clusters.

Available in PDF, EPUB and Kindle. Book excerpt: The remarkable development of organic thin film transistors (OTFTs) has led to their emerging use in active matrix flat-panel displays, radio frequency identification cards, and sensors. Exploring one class of OTFTs, Organic Field-Effect Transistors provides a comprehensive, multidisciplinary survey of the present theory, charge transport studies, synthetic methodology, materials characterization, and current applications of organic field-effect transistors (OFETs). Covering various aspects of OFETs, the book begins with a theoretical description of charge transport in organic semiconductors at the molecular level. It then discusses the current understanding of charge transport in single-crystal devices, small molecules and oligomers, conjugated polymer devices, and charge injection issues in organic transistors. After describing the design rationales and synthetic methodologies used for organic semiconductors and dielectric materials, the book provides an overview of a variety of characterization techniques used to probe interfacial ordering, microstructure, molecular packing, and orientation crucial to device performance. It also describes the different processing techniques for molecules deposited by vacuum and solution, followed by current technological examples that employ OTFTs in their operation. Featuring respected contributors from around the world, this thorough, up-to-date volume presents both the theory behind OFETs and the latest applications of this promising technology.

Topological defects and transport and optical properties are then addressed, and one of the most commonly used transparent conducting polymers, PEDOT:PSS, is described in some detail as a case study.
Download or read book Point Defects in Solids written by James H. Crawford and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 1 of Point Defects in Solids has as its major emphasis defects in ionic solids. Volume 2 now extends this emphasis to semiconductors. The first four chapters treat in some detail the creation, kinetic behavior, inter actions, and physical properties of both simple and composite defects in a variety of semiconducting systems. Also included, as in Vol. 1, are chapters on special topics, namely phonon-defect interactions and defects in organic crystals. Defect behavior in semiconductors has been a subject of considerable interest since the discovery some twenty-five years ago that fast neutron irradiation profoundly affected the electrical characteristics of germanium and silicon. Present-day interest has been stimulated by such semiconductor applications as solar cell power plants for space stations and satellites and semiconductor particle and y-ray detectors, since in both radiation damage can cause serious deterioration. Of even greater practical concern is the need to understand particle damage in order to capitalize upon the develop ing technique of ion implantation as a means of device fabrication. Although the periodic international conferences on radiation effects in semiconductors have served the valuable function of summarizing the extensive work being done in this field, these proceedings are much too detailed and lack the background discussion needed to make them useful to the novice.

Available in PDF, EPUB and Kindle. Book excerpt: This book, first published in 2007, focuses on the application of defects and impurities in current and emerging semiconductor technologies. The role of defects in the evolution of semiconductor technology is now recognized as one of refined control - in density, properties, spatial location, and perhaps even temporal variation during device operating lifetime. The concept of defect engineering has found numerous applications in the fabrication of semiconductors and devices with improved and/or new properties, and new trends extend defect engineering in structures with nm dimensions. This book shows interaction among researchers pursing effective use of defect incorporation and control at various facets of technology and widely different semiconductor materials systems. Topics include: dopant and defect issues in oxide and nitride semiconductors; defect properties, activation and passivation; defects in nanostructures and organic semiconductors; ion implantation and beam processing; defect characterization; heterojunctions and interfaces; process-induced defects; dopants and defects in group-IV semiconductors and defects in devices.
