This book was released on 1992 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research project was to establish a better understanding of in-well and cross-well carrier transport in multiple quantum well (MQW) semiconductors. Carrier emission from both multiple and single quantum well devices have been studied in detail in p-i-n doped MQW SEED-type modulator structures and in waveguides. Simultaneous measurements of electron and hole emission rates has been accomplished for the first time leading to important conclusions concerning thermionic emission models for quantum wells. Extensive modeling of the dynamical optical response relating to cross-well carrier transport has been carried out. Spin relaxation has also been used successfully to monitor carrier dynamics in MQW devices. A new family of mode- locked lasers have been developed for time resolved measurements which are looking extremely attractive as ultrashort pulse sources for GaAs-based optoelectronic devices.

Download or read book Devices Based on Low Dimensional Semiconductor Structures written by M. Balkanski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-dimensional semiconductor quantum structures are a major, high-technological development that has a considerable industrial potential. The field is developing extremely rapidly and the present book represents a timely guide to the latest developments in device technology, fundamental properties, and some remarkable applications. The content is largely tutorial, and the book could be used as a textbook. The book deals with the physics, fabrication, characteristics and performance of devices based on low-dimensional semiconductor structures. It opens with fabrication procedures. The fundamentals of quantum structures and electro-optical devices are dealt with extensively. Nonlinear optical devices are discussed from the point of view of physics and applications of exciton saturation in MQW structures. Waveguide-based devices are also described in terms of linear and nonlinear coupling. The basics of pseudomorphic HEMT technology, device physics and materials layer design are presented. Each aspect is reviewed from the elementary basics up to the latest developments. Audience: Undergraduates in electrical engineering, graduates in physics and engineering schools. Useful for active scientists and engineers wishing to update their knowledge and understanding of recent developments.

Download or read book Femtosecond Time Resolved Studies of High Field Parallel Transport in GaAs Quantum Wells written by W. J. Schaff and published by . This book was released on 1992 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ballistic transport of electrons in semiconductors has recently been a topic of great interest. These studies are important because ballistic transport is expected to play a role in the operation of a number of state-of-the-art semiconductor devices. Ballistic drift in a field-free region of electrons launched across a heterojunction has been observed. In this paper we describe experiments that apply optical spectroscopy to time-resolve the distribution functions of electrons in the presence of a strong electric field applied in the plane of a MQW structure. The carriers are injected with zero initial kinetic energy by a short laser pulse. The exciton field-ionization, electron quasi-ballistic acceleration, field-induced heating, and real-space transfer of electrons into the barrier region of the MQW are observed by monitoring the carrier distribution function using femtosecond-pump continuum-probe techniques.

Available in PDF, EPUB and Kindle. Book excerpt: The development and application of low-dimensional semiconductors have been rapid and spectacular during the past decade. Ever improving epitaxial growth and device fabrication techniques have allowed access to some remarkable new physics in quantum confined structures while a plethora of new devices has emerged. The field of optoelectronics in particular has benefited from these advances both in terms of improved performance and the invention of fundamentally new types of device, at a time when the use of optics and lasers in telecommunications, broadcasting, the Internet, signal processing, and computing has been rapidly expanding. An appreciation of the physics of quantum and dynamic electronic processes in confined structures is key to the understanding of many of the latest devices and their continued development. Semiconductor Quantum Optoelectronics covers new physics and the latest device developments in low-dimensional semiconductors. It allows those who already have some familiarity with semiconductor physics and devices to broaden and expand their knowledge into new and expanding topics in low-dimensional semiconductors. The book provides pedagogical coverage of selected areas of new and pertinent physics of low-dimensional structures and presents some optoelectronic devices presently under development. Coverage includes material and band structure issues and the physics of ultrafast, nonlinear, coherent, intersubband, and intracavity phenomena. The book emphasizes various devices, including quantum wells, visible, quantum cascade, and mode-locked lasers; microcavity LEDs and VCSELs; and detectors and logic elements. An underlying theme is high-speed phenomena and devices for increased system bandwidths.
