This book was released on 1964 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method to measure the quantum efficiency of radiative recombination in uniformly doped ptype gallium arsenide and to study the radiative lifetime has been developed. The method involves measurement of the efficiency (photon yield) of photoluminescence, separation of surface recombination from bulk recombination by varying the absorption length of the excitation light, measurement of electron-diffusion length by the spectral dependence of surface photovoltage and also by the absorption-length dependence of photoluminescence, and a theoretical estimate of the electron mobility. The photon yield was determined from measurement of the relative intensities of the excitation light beam and the photoluminescence beam radiated into a known solid angle, using a calculated correction for refraction and reflection losses involved in the escape of luminescence from the sample.

Download or read book LED Lighting written by Malvin Carl Teich and published by Google Books/Teich Consultants. This book was released on 2024-02-28 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: LED Lighting is a self-contained and introductory-level book featuring a blend of theory and applications that thoroughly covers this important interdisciplinary area. Building on the underlying fields of optics, photonics, and vision science, it comprises four parts. PART I is devoted to fundamentals. The behavior of light is described in terms of rays, waves, and photons. Each of these approaches is best suited to a particular set of applications. The properties of blackbody radiation, thermal light, and incandescent light are derived and explained. The essentials of semiconductor physics are set forth, including the operation of junctions and heterojunctions, quantum wells and quantum dots, and organic and perovskite semiconductors. PART II deals with the generation of light in semiconductors, and details the operation and properties of III-V semiconductor devices (MQWLEDs and μLEDs), quantum-dot devices (QLEDs & WOLEDs), organic semiconductor devices (OLEDs, SMOLEDs, PLEDs, & WOLEDs), and perovskite devices (PeLEDs, PPeLEDs, QPeLEDs, & PeWLEDs). PART III focuses on vision and the perception of color, as well as on colorimetry. It delineates radiometric and photometric quantities as well as efficacy and efficiency measures. It relays the significance of metrics often encountered in LED lighting, including the color rendering index (CRI), color temperature (CT), correlated color temperature (CCT), and chromaticity diagram. PART IV is devoted to LED lighting, focusing on its history and salutary features, and on how this modern form of illumination is deployed. It describes the principal components used in LED lighting, including white phosphor-conversion LEDs, chip-on-board (COB) devices, color-mixing LEDs, hybrid devices, LED filaments, retrofit LED lamps, LED luminaires, and OLED light panels. It concludes with a discussion of smart lighting and connected lighting. Each chapter contains highlighted equations, color-coded figures, practical examples, and reading lists.
Download or read book Selected Works of Professor Herbert Kroemer written by C. K. Maiti and published by World Scientific. This book was released on 2008 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information technology has changed our society radically. Just as the integrated circuits have been the prime mover for electronics, high-speed transistors and semiconductor lasers based on heterostructures are now playing the same role in modern telecommunications. Professor Kroemer's conceptual work on heterostructures began in the early 1950s as he was looking for a way to improve transistor speed and performance. In the 1960s, he applied the same principles to the development of lasers and light-emitting diodes, showing that they could achieve continuous operation at room temperature OCo something thought impossible at that time. His deep fundamental scientific work has had a profound effect on technology and society, transforming and improving our lives.This reprint collection brings together Professor Kroemer's most important papers, presenting a comprehensive perspective of the field. It covers topics ranging from substrate materials, electronic properties, process technology, and devices, to circuits and applications. This reprint collection will help the reader identify the key stages in the development of heterostructure devices and lasers from early research through to its integration in current manufacturing. Devoted to R&D engineers and scientists who are actively involved in extending the nano- and microelectronics roadmap mainly via heterostructure engineering, this volume may also serve as a reference for postgraduate and research students."
