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.

Available in PDF, EPUB and Kindle. Book excerpt: Systematically discusses the growth method, material properties, and applications for key semiconductor materials MOVPE is a chemical vapor deposition technique that produces single or polycrystalline thin films. As one of the key epitaxial growth technologies, it produces layers that form the basis of many optoelectronic components including mobile phone components (GaAs), semiconductor lasers and LEDs (III-Vs, nitrides), optical communications (oxides), infrared detectors, photovoltaics (II-IV materials), etc. Featuring contributions by an international group of academics and industrialists, this book looks at the fundamentals of MOVPE and the key areas of equipment/safety, precursor chemicals, and growth monitoring. It covers the most important materials from III-V and II-VI compounds to quantum dots and nanowires, including sulfides and selenides and oxides/ceramics. Sections in every chapter of Metalorganic Vapor Phase Epitaxy (MOVPE): Growth, Materials Properties and Applications cover the growth of the particular materials system, the properties of the resultant material, and its applications. The book offers information on arsenides, phosphides, and antimonides; nitrides; lattice-mismatched growth; CdTe, MCT (mercury cadmium telluride); ZnO and related materials; equipment and safety; and more. It also offers a chapter that looks at the future of the technique. Covers, in order, the growth method, material properties, and applications for each material Includes chapters on the fundamentals of MOVPE and the key areas of equipment/safety, precursor chemicals, and growth monitoring Looks at important materials such as III-V and II-VI compounds, quantum dots, and nanowires Provides topical and wide-ranging coverage from well-known authors in the field Part of the Materials for Electronic and Optoelectronic Applications series Metalorganic Vapor Phase Epitaxy (MOVPE): Growth, Materials Properties and Applications is an excellent book for graduate students, researchers in academia and industry, as well as specialist courses at undergraduate/postgraduate level in the area of epitaxial growth (MOVPE/ MOCVD/ MBE).

Book excerpt: We have used reflectance-difference spectroscopy (RDS) to examine the surface phases of GaAs(100) during metalorganic chemical vapor deposition (MOCVD). Since the identities of two important surface phases were unknown, we determined their structure and stoichiometry using a variety of surface science techniques. The Type III phase is a newly characterized As-rich (1 X 2)-CH3 reconstruction. The Type II phase is a metastable derivative of the Type I phase. RDS also indicates that the surface during MOCVD has a considerable degree of heterogeneity. Deposition rates were measured over a similar range of conditions and the kinetically-limited regime was found to correlate with the Type III phase. A simple kinetic model was found to quantitatively describe the deposition rates.

Book excerpt: The MOCVD Challenge: Volume 2, A Survey of GaInAsP-GaAs for Photonic and Electronic Device Applications focuses on GaAs systems and devices grown by MOCVD, specifically MOCVD growth of GaAs and related alloys and GaInP for photonic and electronic applications. Along with Volume 1, this book provides a personal account of the author's own pioneering research, an authoritative overview of the development of the MOCVD technique, and the technique's impact on the development of new materials, devices, and their applications. Coverage begins with an introduction to III-V compounds and devices and growth techniques for multilayers and heterostructures. The book then details how an MOCVD system works and how design affects material growth and sourcing of precursor materials. It also examines ^Iin- and ^Iex-situ growth techniques, with the differential reflectivity treatment applied to lattice matched and mis-matched conditions. The author gives an in-depth treatment of the GaInPGaAs system, including optical investigations of quantum wells and superlattices. The book concludes with an up-to-date discussion of the current use, novel developments, and future potential for optical devices, GaAs-based lasers and heterojunctions, and optoelectronic integrated circuits. The MOCVD Challenge is an invaluable introduction and guide for researchers in materials science, applied physics, and electrical engineering, who study the properties and applications of compound (III-V) semiconductor materials. Professor Manijeh Razeghi is director of the Center for Quantum Devices at Northwestern University and leads an internationally renowned research team exploring the use of the MOCVD growth technique. Formerly head of research at Thomson-CSF in France, she was awarded the IBM Europe Science and Technology Prize for her early research into MOCVD.
