Properties of Aluminium Gallium Arsenide


Book Description

The alloy system A1GaAs/GaAs is potentially of great importance for many high-speed electronics and optoelectronic devices, because the lattice parameter difference GaAs and A1GaAs is very small, which promises an insignificant concentration of undesirable interface states. Thanks to this prominent feature, a number of interesting properties and phenomena, such as high-mobility low-dimensional carrier gases, resonant tunnelling and fractional quantum Hall effect, have been found in the A1GaAs/GaAs heterostructure system. New devices, such as modulation-doped FETs, heterojunction bipolar transistors, resonant tunnelling transistors, quantum-well lasers, and other photonic and quantum-effect devices, have also been developed recently using this material system. These areas are recognized as not being the most interesting and active fields in semiconductor physics and device engineering.

Ii-Vi Semiconductor Blue/Green Light Emitters


Book Description

This volume provides one of the first comprehensive reviews combining recent breakthroughs in blue/green semiconductor lasers based on II-VI materials and fundamentally important issues about the development and extension of these lasers to commercial applications. These lasers are on the cutting-edge of technology and could revolutionize areas such as optical information storage and color displays in the next few years.An important focus of this book is on the recent laboratory development of an entirely new class of diode lasers, based on a different family of semiconductor materials, which emit at much shorter wavelengths in the green and blue portion of the spectrum.These new and exciting developments in optoelectronics, which are still undergoing laboratory testing, have the potential of providing a major increase in storage capacity over current CD technology.Besides applications in high-density digital optical storage, other possible aplications for the compact blue-green lasers will be in areas ranging from flat panel displays to multicolor printing to medical diagnostics. Details practical issues of the growth of laser structures by molecular beam epitaxy by pioneers in the industry Explains how the barriers of doping and electrical contact were overcome by using wide bandgap II-VI semiconductors Documents thirty years of research




Ponderings II–VI


Book Description

Ponderings II–VI begins the much-anticipated English translation of Martin Heidegger's "Black Notebooks." In a series of small notebooks with black covers, Heidegger confided sundry personal observations and ideas over the course of 40 years. The five notebooks in this volume were written between 1931 and 1938 and thus chronicle Heidegger's year as Rector of the University of Freiburg during the Nazi era. Published in German as volume 94 of the Complete Works, these challenging and fascinating journal entries shed light on Heidegger's philosophical development regarding his central question of what it means to be, but also on his relation to National Socialism and the revolutionary atmosphere of the 1930s in Germany. Readers previously familiar only with excerpts taken out of context may now determine for themselves whether the controversy and censure the "Black Notebooks" have received are deserved or not. This faithful translation by Richard Rojcewicz opens the texts in a way that captures their philosophical and political content while disentangling Heidegger's notoriously difficult language.

Studies on the Origin of Harmonic Tonality


Book Description

Carl Dahlhaus was without doubt the premier musicologist of the postwar generation, a giant whose recent death was mourned the world over. Translated here for the first time, this fundamental work on the development of tonality shows his complete mastery of the theory of harmony. In it Dahlhaus explains the modern concepts of harmony and tonality, reviewing in the process the important theories of Rameau, Sechter, Ftis, Riemann, and Schenker. He contrasts the familiar premises of chordal composition with the lesser known precepts of intervallic composition, the basis for polyphonic music in the late Middle Ages and Renaissance. Numerous quotations from theoretical treatises document how early music was driven forward not by progressions of chords but by simple progressions of intervals. Exactly when did composers transform intervallic composition into chordal composition? Modality into tonality? Dahlhaus provides extensive analyses of motets by Josquin, frottole by Cara and Tromboncino, and madrigals by Monteverdi to demonstrate how, and to what degree, such questions can be answered. In his bold speculations, in his magisterial summaries, in his command of eight centuries of music and writings on music, and in his deep understanding of European history and culture, Carl Dahlhaus sets a standard that will seldom be equalled. Originally published in 1990. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
