This book was released on 1992 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strained alloy InGaAs/GaAs multiple quantum well structures (MQWs), on GaAs substrates, are being investigated' for use in optical modulators, low-threshold diode lasers, photodetectors and other opto-electronic devices operating near 1 um. Attempts are being made to cover the 0.9-1.1 am spectral range by varying well-widths and/or alloy mole-fraction and by growing such structures on superlattice or alloy buffer layers. Special problems, however, are posed in growing these strained ternary alloy quantum wells with high quality by epitaxial techniques. Alloy concentration is difficult to reproduce, and alloy-disorder introduces an additional line-broadening contribution and non-uniformity into the materials. The critical thickness parameter places an upper limit on the indium mole-fraction (and thereby the strain) for growth directly on GaAs, restricting the flexibility in varying the well width for increased spectral coverage. Typically, this mole-fraction must be less than 0.2, and the lattice-parameter mismatch below 2%, for well-widths -10 nm. Here, we focus on structures in which each quantum well consists of an ordered InAs/GaAs short-period superlattice as an attractive alternative to the random InGaAs alloy structures. These all-binary MQWs are highly-strained (7% lattice parameter mismatch) and can accommodate high average indium mole-fraction (30-40%) in wide wells (10-20 nm) without evidence of strain relaxation due to misfit dislocation formation.

Available in PDF, EPUB and Kindle. Book excerpt: It is widely recognized that an understanding of the optical pro perties of matter will give a great deal of important information re levant to the fundamental physical properties. This is especially true in semiconductor physics for which, due to the intrinsic low screening of these materials, the optical response is quite rich. Their spectra reflect indeed as well electronic as spin or phonon transitions. This is also in the semiconductor field that artificial structures have been recently developed, showing for the first time specific physical properties related to the low dimentionality of the electronic and vi bronic properties : with this respect the quantum and fractional quan tum Hall effects are among the most well known aspects. The associated reduced screening is also a clear manifestation of these aspects and as such favors new optical properties or at least significantly enhan ces some of them. For all these reasons, it appeared necessary to try to review in a global way what the optical investigation has brought today about the understanding of the physics of semiconductors. This volume collects the papers presented at the NATO Advanced study Inst i tut e on "Optical Properties of Semiconductors" held at the Ettore Majorana Centre, Erice, Sicily on March 9th to 20th, 1992. This school brought together 70 scientists active in research related to optical properties of semiconductors. There were 12 lecturers who pro vided the main contributions .

This book was released on 2012-12-06 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the lectures delivered at the NATO Advanced Study Institute on "Physics and Applications of Quantum Wells and Superlattices", held in Erice, Italy, on April 21-May 1, 1987. This course was the fourth one of the International School of Solid-State Device Research, which is under the auspices of the Ettore Majorana Center for Scientific Culture. In the last ten years, we have seen an enormous increase in re search in the field of Semiconductor Heterostructures, as evidenced by the large percentage of papers presented in recent international conferences on semiconductor physics. Undoubtfully, this expansion has been made possible by dramatic advances in materials preparation, mostly by molecular beam epitaxy and organometallic chemical vapor deposition. The emphasis on epitaxial growth that was prevalent at the beginning of the decade (thus, the second course of the School, held in 1983, was devoted to Molecular Beam Epitaxy and Heterostructures) has given way to a strong interest in new physical phenomena and new material structures, and to practical applications that are already emerging from them.
