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.

Organic Semiconductor Heterojunctions and Its Application in Organic Light-Emitting Diodes by Dongge Ma,Yonghua Chen Pdf

This book systematically introduces the most important aspects of organic semiconductor heterojunctions, including the basic concepts and electrical properties. It comprehensively discusses the application of organic semiconductor heterojunctions as charge injectors and charge generation layers in organic light-emitting diodes (OLEDs). Semiconductor heterojunctions are the basis for constructing high-performance optoelectronic devices. In recent decades, organic semiconductors have been increasingly used to fabricate heterojunction devices, especially in OLEDs, and the subject has attracted a great deal of attention and evoked many new phenomena and interpretations in the field. This important application is based on the low dielectric constant of organic semiconductors and the weak non-covalent electronic interactions between them, which means that they easily form accumulation heterojunctions. As we know, the accumulation-type space charge region is highly conductive, which is an important property for highly efficient charge generation in their application as charge injector and charge generation layer in OLEDs. This book serves as a valuable reference for researchers and as a textbook for graduate students focusing on the study and development of OLED for display and lighting.

Organic Electronic Devices by Klaus Petritsch Pdf

This book is a collection of selected papers and book sections on recent developments and research on organic electronic devices. Most articles were published in the years 2015-2017. While organic semiconductors tend to lack somewhat behind their inorganic counterparts with respect to charge-carrier mobility, stability, and efficient operation, the prospect of low cost, large-scale production of flexible electronic devices continues to fuel increasing research. Organic light emitting devices (OLEDs) have already found commercial applications in modern large screen television/touch-screens, and they are now entering the market for lighting applications too. After a brief introduction of organic semiconductor devices with an overview of the selected papers by the editor, the chosen publications are organized into four thematic sections.Section 1 focuses on light-sensing devices. Organic compounds tend to absorb light much stronger than inorganic materials for a given wavelength range. The first paper reviews the development and known physical principles of organic solar energy harvesting devices. While solar cells are designed to convert sunlight into electric power, photodetectors only need to detect light. They can therefore use an external bias voltage to improve their light-sensing characteristics. This enables their use as spectrometer-on-a-chip that opens the door to many analytical/biological applications, which are discussed at the end of this section. Section 2 is dedicated to light-emitting device structures. The first part summarizes the process of light extraction and polarization, as well as improvements using interference effects due to regular nanoscale structuring (photonic structures). This is followed by measures to improve not only OLEDs, but also organic lasers, and the properties of organic light emitting field-effect transistors. Section 3, light-independent devices, is dedicated to device types that do not fit into any of the first two categories. This section includes true bulk", flexible, yet robust mixed ionic-electronic conductor paper, which may enable mass power storage a very sensitive ionic thermo-sensor (transistor), a simultaneous temperature/pressure sensor, and an ultrathin organic CMOS D-flip-flop circuit.Section 4 summarizes recent progress in organic device manufacturing techniques. Discussed topics include: the accurate alignment during high-throughput roll-to-roll printing, directional self-assembling of polymer chains, patterning of organic conductors on textiles, spray printing of organic semiconducting single crystals, solution printing of organic semiconductor blends that show transport properties on par with single crystals.

Organic Light-Emitting Devices by Joseph Shinar Pdf

Although it has long been possible to make organic materials emit light, it has only recently become possible to do so at the level and with the efficiency and control necessary to make the materials a useful basis for illumination or displays. The early electroluminescent devices provided reasonably bright light, but required high operating voltages, produced only a narrow range of colors, and had severely limited lifetimes. Recent developments, however, make it possible to manufacture organic light-emitting devices that are thin, bright, efficient, and stable and that produce a broad range of colors. This book surveys the current status of the field. It begins with an overview of the physics and chemistry of organic light emitting devices by J. Shinar and V. Savvateev. Subsequenbt chapters discuss the design of molecular materials for high performance devices (C. Adachi and T. Tsutsui) and chemical degradation and physical aging (K. Higginson, D. L. Thomsen, B. Yang, and F. Papadimitrakopoulos). A. Dodabalapur describes microcavity OLEDs, and Y. Shi, J. Liu, and Y. Yang discuss polymer morphology and device performance. Various aspects of devices based on polyparaphenylene vinylenes are discussed in chapters by N.C. Greenham and R.H. Friend and by H. Chayet, V. Savvateeyv, D. Davidov and R. Neumann. Chapters by S. Tasch, W. Graupner, and G. Leising and by Y. Z. Wang, D. Gebler, and A. J. Epstein describe OLEDs based on poly(paraphenylene) and poly(pyridine), respectively. The book concludes with a chapter on polyfluorene-based devices, which show great promise for producing light in all colors from blue to red.

Low Threshold Organic Semiconductor Lasers by Yue Wang Pdf

This thesis focuses on two areas - the development of miniature plastic lasers that can be powered by LEDs, and the application of these lasers as highly sensitive sensors for vapours of nitroaromatic explosives (e.g. TNT). Polymer lasers are extremely compact visible lasers; the research described in the thesis is groundbreaking, driving forward the technology and physical understanding to allow these lasers to be routinely pumped by a single high-power LED. A notable advance in the work is the demonstration of nanoimprinted polymer lasers, which exhibit the world's lowest pump threshold densities by two orders of magnitude. The thesis also advances the application of these compact, novel lasers as highly sensitive detectors of explosive vapours, demonstrating that rapid detection can be achieved when microporous polymers are used. This work also demonstrates a prototype CMOS-based microsystem sensor for explosive vapours, exploiting a new detection approach.
