Download or read book Two step MOVPE in situ etching and buried implantation applications to the realization of GaAs laser diodes written by Pietro della Casa and published by Cuvillier Verlag. This book was released on 2021-03-25 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is about two-step epitaxial growth using metalorganic vapor-phase epitaxy (MOVPE) for the realization of edge-emitting near-infrared laser diodes. The fabricated gallium arsenide-based devices fall into two categories: high-power lasers (watt range, multimodal) and tunable lasers (milliwatt range, monomodal). Common to both cases is that surface contamination – particularly that due to oxygen – needs to be removed before regrowth. Thus, in-situ etching with carbon tetrabromide (CBr4) is first studied. The experimental results include kinetic data, the effects of different etching conditions as well as substrate characteristics, and the effectiveness in reducing surface contamination. These investigations pave the way to devices based on 2-step epitaxy combined with in-situ etching. Correspondingly, thermally-tuned SG-DBR lasers operating around 975 nm have been successfully realized, obtaining a tuning range of 21 nm. In addition, the possibility of using electronic tuning in similar devices has been explored. High-power broad-area lasers have also been realized, using two-step epitaxy combined with ex-situ and in-situ etching, to create a buried, shallow “mesa” containing the active zone. This approach allows introducing lateral electrical and optical confinement, and – simultaneously – non-absorbing mirrors at the laser facets. Additionally, a different strategy to create a buried current aperture is presented, which is based on ion implantation followed by epitaxial regrowth. This enables to improve device performance and simultaneously introduce non-absorbing mirrors at the facets with correspondingly increased reliability.

This book was released on 2012-12-02 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frontiers of Materials Research/Electronic And Optical Materials: Volume I is part of a five-volume compilation of the proceedings of C-MRS International 1990 Conference held in Beijing, China. The said conference discusses the areas of research in materials science. The book is divided into three parts. Part 1 covers topics involved in the development and progress of materials such as the focused beam ion; intermetallic compounds; polymers; and the application of computers in the field. Part 2 includes studies related to high Tc superconductors such as methods related to the field; the effects of oxygen and partial pressure on the properties of superconducting; and the study of superconductivity and crystallography. Part 3 presents papers related optoelectronic materials and functional crystals, which are mostly about the growth, properties, and uses of the different crystals being studied in each paper. The text is recommended for scientists and engineers who would like to know more about the field of materials science, especially those who would like to be involved in materials research.

Download or read book Chemistry for Electronic Materials written by K.F. Jensen and published by Elsevier. This book was released on 1993-03-09 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemical aspects of materials processing used for electronic applications, e.g. Si, III-V compounds, superconductors, metallization materials, are covered in this volume. Significant recent advances have occurred in the development of new volatile precursors for the fabrication of III-V semiconductor and metal [Cu, W] films by OMCVD. Some fundamentally new and wide-ranging applications have been introduced in recent times. Experimental and modeling studies regarding deposition kinetics, operating conditions and transport as well as properties of films produced by PVD, CVD and PECVD are discussed. The thirty papers in this volume report on many other significant topics also. Research workers involved in these aspects of materials technology may find here some new perspectives with which to augment their projects.

This book was released on 1989 with total page 1298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
