High electron mobility transistor (HEMT) has better performance potential than the conventional MOSFETs. Further, InAs is a perfect candidate for the HEMT device architecture owing to its peak electron mobility. Advanced Indium Arsenide-based HEMT Architectures for Terahertz Applications characterizes the HEMT based on InAs III-V material to achieve outstanding current and frequency performance. This book explains different types of device architectures available to enhance performance including InAs-based single gate (SG) HEMT and double gate (DG) HEMT. The noise analysis of InAs-based SG and DG-HEMT is also discussed. The main goal of this book is to characterize the InAs device to achieve terahertz frequency regime with proper device parameters.Features:Explains the influence of InAs material in the performance of HEMTs and MOS-HEMTs.Covers novel indium arsenide architectures for achieving terahertz frequenciesDiscusses impact of device parameters on frequency responseIllustrates noise characterization of optimized indium arsenide HEMTsIntroduces terahertz electronics including sources for terahertz applications.This book is of special interest to researchers and graduate students in Electronics Engineering, High Electron Mobility Transistors, Semi-conductors, Communications, and Nanodevices.

This textbook presents the fundamental concepts and application of optical mineralogy in a very simple, systematic, and comprehensive way. The book is organized into 2 parts: Part I deals with the theory and techniques, and Part II provides a description of the optical properties of common minerals. The book is written in a lucid manner so that students are able to understand the realization behind the concepts in optics and the methods employed to elicit information about the interior of mineral crystals. All the subject fundamentals and related derivations are discussed in an easy and comprehensive way to make the students strong in the basics of optical mineralogy. The key features lie in the illustrations, examples, and questions at the end of each chapter to provide students with practical usage insights into optical mineralogy. The book benefits students who are taking introductory courses in optics to characterize rock minerals.

This volume builds upon the successful book Lanthanide Luminescence published in the Springer Series on Fluorescence in 2011. Since its publication, the field of lanthanide spectroscopy and the areas in which the light emission properties of the f-elements are used have experienced substantial advances. The luminescence properties of lanthanide ions make them unique candidates for a myriad of optical applications. This book highlights and reviews the latest research in areas ranging from luminescence thermometry to imaging, sensing and photonic applications of these fascinating elements. Each chapter provides a comprehensive introduction to a specific area of application of lanthanide luminescence and extensively reviews seminal papers and current research literature. Given its interdisciplinary scope, the book appeals to scientists and advanced students in physics, chemistry and materials science interested in compounds and materials with optical properties.

This book is on the nonlinear random medium analysis that includes subtopics of terahertz imaging, inverse scattering, plasmonics, quantum optics/communication laser modes, and terahertz photonic antennas. Here in this book, a mathematical framework is developed to analyze the impact of dimensions and chemical potential on nano-antenna channels.

This book comprises a detailed consideration of novel approaches developed in the field of frequency conversion of laser sources in laser-induced plasmas during the last few years. The aim of the book is to support researchers and other readers in their development in the area of high-order nonlinear spectroscopy. Particularly, the advanced studies of nanoparticles and quantum dots for the formation of new sources of radiation in different short-wavelength spectral ranges show the ways to further implement the specific features of small-sized species in a relatively new field of study-laser ablation induced high-order harmonics generation spectroscopy.Researchers involved in the development of new methods of frequency conversion will benefit from finding the most recent advances in this field. Undergraduate students will discover interesting information about recent findings in plasma harmonic research. Additionally, the usefulness of the book will be demonstrated by the potential applications of the new knowledge developed during recent years for ultrafast pulse generation using the proposed schemes of plasma-light interaction. Thus, the audience may also include those researchers involved in state-of-the-art developments in attophysics. Additionally, any professionals interested in the application of the advanced techniques for material science will also benefit from updating their knowledge of new methods of material studies using high-order nonlinear spectroscopy.

Nachdem Wilhelm Ostwald die Universität Leipzig 1906 wegen anhaltender Streitigkeiten mit der philosophischen Fakultät verlassen hatte, ließ er sich in Großbothen als Privatgelehrter nieder. Hier entwickelte er seine Farbenlehre. 1923, in einem wirtschaftlich und politisch krisenhaften Jahr, erschien seine Farbkunde. Mit diesem Werk wandte er sich an eine breite Zielgruppe ¿ an ¿Chemiker, Physiker, Naturforscher, Ärzte, Physiologen, Psychologen, Koloristen, Farbtechniker, Drucker, Keramiker, Färber, Weber, Maler, Kunstgewerbler, Musterzeichner, Plakatkünstler und Modisten¿. Er stellt zunächst die bisher beschriebenen Farblehren und Theorien kritisch bewertend vor. In weiteren Kapiteln werden das Licht, die Vorgänge des Sehens und besonders ausführlich die Farben beschrieben. Als ¿Angewandte Farbkunde¿ behandelt er die Messung der Farben, physikalisch-chemische und psychophysische Verhältnisse sowie die Farbe als Darstellungsmittel und die Harmonie der Farben mit Beschreibungen des Farbtonkreises, Vorschläge für einen Normenatlas mit praktischen Ausführungsformen.Ostwald schuf damit die Grundlagen für weit verbreitete Anwendungen, die im Kommentarteil ausführlich vorgestellt werden.
