Organic Light Emitting Diodes (Hardcover) $385.4 Addressing the development of the organic light emitting diode (OLED) based on rare-earth and transition-metal complexes—Europium, Terbium, Ruthenium, and Rhenium—this unique perspective explains how these materials can be used to build organic-LEDs, from chemistry synthesis to device operation and the related charge transfer and confinement. Examining how organic materials can be used to build organic-LEDs, the relationship between the chemistry molecule "design," and state-of-the-art and expected pathways, this intelligent report provides intensive experimental results for scientists and engineers working in this new OLED framework, while maintaining a didactic utility for graduation students and teachers studying optoelectronics.

Roentgen Rays and Phenomena of the Anode and Cathode $22.69 Originally published in 1896 much of the information in this early works is still useful and practical today. Preface: In addition to the illustrated feature for exhibiting the nature and practical application of Xrays, and for simplifying the descriptions, the book involves the disclosure of the facts and principles relating to the phenomena occurring between and around charged electrodes, separated by different gaseous media at various pressures. The specific aim is the treatment of the radiant energy developed within and from a discharge tube, the only source of Xrays....... Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork. Author: Thompson, Edward P.

Polymer Light Emitting Diodes Based on Polyfluorenes $138.61 This work is devoted to the study on Polymer Light Emitting Diodes (PLEDs) based on polyfluorenes, a promising class of semiconductive polymers for lightemitting diode applications. It covers theories of PLEDs, literature overview of polyfluorenebased lightemitting diodes, as well as research results by the authors. In this study, several types of PLED devices based on neat polyfluorenes or polyfluorene blends were designed, fabricated, and characterized. The electrical characteristics of two neat polyfluorenes were simulated via using space charge limited current theory for the holeonly case and/or exploiting a commercial software package.

Light-Emitting Diodes (Hardcover) $186.1 Revised and fully up-dated, the second edition of this graduate textbook offers a comprehensive explanation of the technology and physics of LEDs such as infrared, visible-spectrum, ultraviolet, and white LEDs made from III-V semiconductors. Elementary properties such as electrical and optical characteristics are reviewed, followed by the analysis of advanced device structures. With nine additional chapters, the treatment of LEDs has been vastly expanded, including new material on device packaging, reflectors, UV LEDs, III-V nitride materials, solid-state sources for illumination applications, and junction temperature. Radiative and non-radiative recombination dynamics, methods for improving light extraction, high-efficiency and high-power device designs, white-light emitters with wavelength-converting phosphor materials, optical reflectors, and spontaneous recombination in resonant-cavity structures are discussed in detail. With exercises, solutions, and illustrative examples, this textbook will be of interest to scientists and engineers working on LEDs and graduate students in electrical engineering, applied physics, and materials science.

Light Emitting Silicon for Microphotonics $380.76 A fascinating insight into the stateoftheart in silicon microphotonics and on what we can expect in the near future. The book presents an overview of the current understanding of getting light from silicon. It concentrates mainly on low dimensional silicon structures, like quantum dots, wires and wells, but covers also alternative approaches like porous silicon and the doping of silicon with rareearths. The emphasis is on the experimental and theoretical achievements concerning the optoelectronic properties of confined silicon structures obtained during recent years. Silicon based photonic crystals are in particular considered. An in depth discussion of the route towards a silicon laser is presented. Author: Ossicini, Stephano/ Ossicini, S./ Pavesi, L.

Anode $81.25 An anode is an electrode through which electric current flows into a polarized electrical device. Mnemonic: ACID (Anode Current Into Device). Electrons flow in the opposite direction to the electric current (flow of hypothetical positive charge). A widespread misconception is that anode polarity is always positive. This is often incorrectly inferred from the correct fact that in all electrochemical devices negatively charged anions move towards the anode (hence their name) and/or positively charged cations move away from it. In fact anode polarity depends on the device type, and sometimes even in which mode it operates, as per the above electric current directionbased universal definition.

WHAT IS OLED?
Short for organic light-emitting diode, a display device that sandwiches carbon-based films between two charged electrodes, one a metallic cathode and one a transparent anode, usually being glass.

The organic films consist of a hole-injection layer, a hole-transport layer,
an emissive layer and an electron-transport layer. When voltage is applied to the OLED cell, the injected positive and negative charges recombine in the emissive layer and create electro luminescent light. Unlike LCDs, which require backlighting, OLED displays are emissive devices - they emit light rather than modulate transmitted or reflected light.

OLED technology was invented by Eastman Kodak in the early 1980s. It is beginning to replace LCD technology in handheld devices such as PDAs and cellular phones because the technology is brighter, thinner, faster and lighter than LCDs, use less power, offer higher contrast and are cheaper to manufacture. An important step in the evolutionary process began with the use of thin-film organic layers. The first EL thin-film device used a single organic layer sandwiched between two injecting electrodes.

OLEDs are the latest and most promising buzzwords in display technology.
To give you an idea of their potential, imagine a cardboard-thin TV screen.
Now imagine that you can roll up your TV, put it away or carry it wherever
you go.
Automatically, you start appreciating why millions, if not billions, of
dollars are being poured into OLED research every year.
