This book was released on 1997-01-01 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical Studies have been conducted upon CdGeAs2 and ZnGeP2, two of the most promising semiconductors being developed for mid-infrared non-linear optics applications. These experiments included photoluminescence (PL) studies of both compounds as well as photoreflectance (PR) measurements upon CdGeAs2. In addition, Hall effect measurements were carried out upon CdGeAs2, to aid in interpretation of the optical data. PL was measured as a function of laser power, sample temperature, and crystal orientation for CdGeAs2. One broad weak peak near 0.38 eV, and another somewhat narrower and often far brighter peak near 0.57 eV were found by low temperature (4 K) PL measurements. Strongly polarized PL was observed with the E field of the PL parallel to the material's c-axis. A polarization ratio as high as 6:1 was observed. PL on ZnGeP2 in the mid-IR revealed a previously unreported PL peak near 0.35 eV. PR measurements on CdGeAs2 allowed the estimation of the bandgap as a function of temperature. Hall effect measurements on CdGeAs2 reveals the dominant acceptor level lies about 120 meV above the valence band.

This book was released on 2010-03-14 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, with the advent of fine line lithographical methods, molecular beam epitaxy, organometallic vapour phase epitaxy and other experimental techniques, low dimensional structures having quantum confinement in one, two and three dimensions (such as ultrathin films, inversion layers, accumulation layers, quantum well superlattices, quantum well wires, quantum wires superlattices, magneto-size quantizations, and quantum dots) have attracted much attention not only for their potential in uncovering new phenomena in nanoscience and technology, but also for their interesting applications in the areas of quantum effect devices. In ultrathin films, the restriction of the motion of the carriers in the direction normal to the film leads to the quantum size effect and such systems find extensive applications in quantum well lasers, field effect transistors, high speed digital networks and also in other quantum effect devices. In quantum well wires, the carriers are quantized in two transverse directions and only one-dimensional motion of the carriers is allowed.

Available in PDF, EPUB and Kindle. Book excerpt: Since Sorby published his observations on the structures of steels in 1863, the optical microscope has become one of the most widely used and versatile instruments for examining the structures of engineering materials. Moreover, to examine the diverse range of materials encountered, it must be used in both the reflected-light and transmitted-light forms, and with polarized light. It is complementary to, but not superseded by, the wide range of electron-optical instruments that are now used. Despite its extensive use, it has been described as the most misused, abused, and misunderstood of scientific instruments, for it will produce an image of a sort no matter how badly it is used. To use it effectively, even in its simplest applications, a knowledge of the simple theory of the microscope is necessary, for the theory shows and explains how it should be used. Thus my aim has been to give a simple and, where possible, quantitative account of both the theory and the use of the microscope, including the various special techniques for which it can be used. But, no matter how effectively the microscope is used, if the specimen is inadequately prepared the results of examination will be of doubtful value.

Book Synopsis Optical Properties of III–V Semiconductors by : Heinz Kalt
Download or read book Optical Properties of III–V Semiconductors written by Heinz Kalt and published by Springer. This book was released on 2012-10-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is concerned with the III-V bulk and low-dimensional semiconductors, with the emphasis on the implications of multi-valley bandstructures for the physical mechanisms essential for opto-electronic devices. The optical response of such semiconductor materials is determined by many-body effects such as screening, gap narrowing, Fermi-edge singularity, electron-hole plasma and liquid formation. Consequently, the discussion of these features reflects such interdependencies with the dynamics of excitons and carriers resulting from intervalley coupling.

Book Synopsis Optical Phenomena in Semiconductor Structures of Reduced Dimensions by : D.J. Lockwood
Download or read book Optical Phenomena in Semiconductor Structures of Reduced Dimensions written by D.J. Lockwood and published by Springer. This book was released on 2012-03-01 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remarkable advances in semiconductor growth and processing technologies continue to have a profound impact on condensed-matter physics and to stimulate the invention of novel optoelectronic effects. Intensive research on the behaviors of free carriers has been carried out in the two-dimensional systems of semiconductor heterostructures and in the one and zero-dimensional systems of nanostructures created by the state-of-the-art fabrication methods. These studies have uncovered unexpected quantum mechanical correlations that arise because of the combined effects of strong electron-electron interactions and wave function confinement associated with reduced dimensionality. The investigations of these phenomena are currently at the frontiers of condensed-matter physics. They include areas like the fractional quantum Hall effect, the dynamics of electrons on an ultra short (femtosecond) time scale, electron behavior in quantum wires and dots, and studies of electron tunneling phenomena in ultra small semiconductor structures. Optical techniques have made important contributions to these fields in recent years, but there has been no coherent review of this work until now. The book provides an overview of these recent developments that will be of interest to semiconductor materials scientists in university, government and industrial laboratories.
Book Synopsis Radiative Properties of Semiconductors by : Nuggehalli M. Ravindra
Download or read book Radiative Properties of Semiconductors written by Nuggehalli M. Ravindra and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical properties, particularly in the infrared range of wavelengths, continue to be of enormous interest to both material scientists and device engineers. The need for the development of standards for data of optical properties in the infrared range of wavelengths is very timely considering the on-going transition of nano-technology from fundamental R&D to manufacturing. The recent progress in two-dimensional materials is an example of this evolution in materials science and engineering. Radiative properties play a critical role in the processing, process control and manufacturing of semiconductor materials, devices, circuits and systems. The design and implementation of real-time, non-contact process monitoring and control methods in manufacturing, such as multi-wavelength imaging pyrometry, spectroscopic ellipsometry and reflectometry, require the knowledge of the radiative properties of materials. The design and manufacturing of sensors, imagers, waveguides, filters, antireflection coatings and lenses, operating in the infrared range of wavelengths, requires a reliable database of the radiative properties of materials. This book reviews the optical properties of various semiconductors in the infrared range of wavelengths. Some fundamental and experimental studies of the radiative properties of semiconductors are presented. Previous studies, potential applications and future developments are outlined. In chapter 1, an introduction to the radiative properties is presented. A brief overview of the optical and thermal properties is presented in chapter 2. Examples of the instrumentation for the measurements of the radiative properties are described in chapter 3. In chapters 4-13, case studies of the radiative properties of several semiconductors are elucidated. The modeling and applications of these properties are explained in chapters 14 and 15, respectively. In chapter 16, examples of the global infrastructure for these measurements are illustrated.
