This book was released on 2006 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen incorporation into GaAs has received much attention in the last decade, because of its application to long-wavelength lasers. However, nitrogen incorporation into GaP (100) has not received much attention to date despite the promising application of this material system to yellow-amber-red light-emitting diodes. In order to investigate the not yet well-studied (Al, In, Ga)NP material system, we use gas-source molecular beam (MBE), in which nitrogen radicals are used as nitrogen precursor, to grow these mixed group-V alloy semiconductors with excellent crystallinity. This dissertation is divided into two major parts. In the first part we describe the growth and characterization of the (Al, In, Ga)NP material system. Optical and structural properties of GaNP bulk layers, AlGaNP bulk layers, and InGaNP quantum wells are studied. The dependence of the GaNP band gap vs. nitrogen concentration and temperature dependent PL are analyzed. For AlGaNP layers, using a thermodynamic approach we explain the difference between nitrogen incorporation into GaP and AlP. The dependence of the emission wavelength vs. nitrogen and indium compositions is studied for InGaNP QWs. The electron effective mass is determined for InGaNP materials with different indium concentration. The conduction and valence band offsets are calculated for the InGaNP/GaP heterojunction. In the second part, we describe LED chip fabrication and contacts optimization. development of n-type and p-type contacts is discussed. A description of LED chip processing optimization is given for a p-i-n diode structure. The band offsets are compared for (Al, In, Ga)NP-based LED structures and conventional AlInGaP-based LED structures; they are 2-3 times higher in LEDs based on the (Al, In, Ga)NP material system. Growth and fabrication results for bulk GaNP-based amber LEDs are discussed. Color stability (electroluminescence peak wavelength shift vs. current) is compared for GaNPbased LEDs and AlInGaP-based LEDs; the wavelength shift of (Al, In, Ga)NP-based LED chips is ~ 6 times less than that of AlInGaP-based LED chips, in the drive current range of 10 - 60 mA. The influence of In concentration in InGaNP QWs on EL properties of LED chips is reported. Single and multiple InGaNP QW-based LEDs are studied.

This book was released on 2012-12-06 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Study Institute on "Molecular Beam Epitaxy (MBE) and Heterostructures" was held at the Ettore Majorana Center for Scientific Culture, Erice, Italy, on March 7-19, 1983, the second course of the International School of Solid-State Device Re search. This volume contains the lectures presented at the Institute. Throughout the history of semiconductor development, the coupling between processing techniques and device structures for both scientific investigations and technological applications has time and again been demonstrated. Newly conceived ideas usually demand the ultimate in existing techniques, which often leads to process innova tions. The emergence of a process, on the other hand, invariably creates opportunities for device improvement and invention. This intimate relationship between the two has most recently been witnessed in MBE and heterostructures, the subject of this Institute. This volume is divided into several sections. Chapter 1 serves as an introduction by providing a perspective of the subject. This is followed by two sections, each containing four chapters, Chapters 2-5 addressing the principles of the MBE process and Chapters 6-9 describ ing its use in the growth of a variety of semiconductors and heteros tructures. The next two sections, Chapters to-II and Chapters 12-15, treat the theory and the electronic properties of the heterostructures, respectively. The focus is on energy quantization of the two dimensional electron system. Chapters 16-17 are devoted to device structures, including both field-effect transistors and lasers and detec tors.

Download or read book Molecular Beam Epitaxy written by Robin F.C. Farrow and published by Elsevier. This book was released on 1995-12-31 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, the editor and contributors describe the use of molecular beam epitaxy (MBE) for a range of key materials systems that are of interest for both technological and fundamental reasons. Prior books on MBE have provided an introduction to the basic concepts and techniques of MBE and emphasize growth and characterization of GaAs-based structures. The aim in this book is somewhat different; it is to demonstrate the versatility of the technique by showing how it can be utilized to prepare and explore a range of distinct and diverse materials. For each of these materials systems MBE has played a key role both in their development and application to devices.

This book was released on 1989 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research program on the growth by Molecular Beam Epitaxy of Hg- based alloys and heterostructures carried out in the Microphysics Laboratory at the University of Illinois at Chicago and supported by this contract has been extremely successful. Tremendous progress has been achieved towards the improvement of HgCdTe and related heterostructures in terms of structural, electrical and optical properties. A very important step has been passed through in the control of the twinning process during the growth in the (111)B orientation. Furthermore, it has been clearly established for the first time that twins or related dislocations are acting as acceptors in HgCdTe and are detrimental for diode performance, what was suspected but never proved until our conclusive experiments.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrawide bandgap (UWBG) semiconductors, especially those in the III-nitride family of materials with their exceptional electronic, optical, and thermal properties, will play a highly important role in the next generation of ultraviolet photonic and high power electronic devices. Currently, the performance and utilization of many UWBG materials in device applications is hampered by fundamental materials challenges with growth and doping. This thesis covers the growth and materials properties of two III-nitride UWBG materials, primarily grown by molecular beam epitaxy (MBE). First, hexagonal boron nitride, a two dimensional, layered material with unique optical properties and potential applications in van der Waals-based devices and heterostructures will be discussed. Second, recent work on aluminum nitride (AlN) and aluminum gallium nitride (AlGaN) alloys will be presented.This work begins with an investigation into the high temperature MBE growth of hBN on several substrates. The layers show improved quality over previous reports and are thoroughly characterized. Next, the optical properties of these hBN films, as well as those of bulk doped hBN crystals, are investigated by cryogenic deep UV photoluminescence. Several new emission characteristics are identified and studied in these hBN materials, including carbon-induced luminescence, the direct bandgap transition of monolayer hBN, and single photon emission from hBN defects. Transitioning to the AlGaN platform, the growth of AlN and AlGaN by MBE on high quality single crystalline bulk AlN substrates is outlined and expanded upon, including an analysis of AlGaN doping with Si and Mg. The MBE growth, doping, and electron transport of heavily Si-doped, high Al mole fraction Al- GaN on bulk AlN is investigated, revealing upper practical limits to both Al mole fraction and Si doping density for high conductivity n-type films. In addition to this work on material growth and characterization, several AlGaN-based devices, an optically pumped UV laser and a Schottky barrier diode, will be introduced and discussed. These devices directly benefit from the preceding advances in AlGaN growth and doping. Finally, initial exploratory investigations and results on cubic phase BN as well as boron aluminum nitride alloys will be presented.

Book Synopsis Molecular Beam Epitaxy by : Brian R. Pamplin
Download or read book Molecular Beam Epitaxy written by Brian R. Pamplin and published by Elsevier. This book was released on 2017-08-31 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Beam Epitaxy introduces the reader to the use of molecular beam epitaxy (MBE) in the generation of III-V and IV-VI compounds and alloys and describes the semiconductor and integrated optics reasons for using the technique. Topics covered include semiconductor superlattices by MBE; design considerations for MBE systems; periodic doping structure in gallium arsenide (GaAs); nonstoichiometry and carrier concentration control in MBE of compound semiconductors; and MBE techniques for IV-VI optoelectronic devices. The use of MBE to fabricate integrated optical devices and to study semiconductor surface and crystal physics is also considered. This book is comprised of eight chapters and opens with an overview of MBE as a crystal growth technique. The discussion then turns to the deposition of semiconductor superlattices of GaAs by MBE; important factors that must be considered in the design of a MBE system such as flux uniformity, crucible volume, heat shielding, source baffling, and shutters; and control of stoichiometry deviation in MBE growth of compound semiconductors, along with the effects of such deviation on the electronic properties of the grown films. The following chapters focus on the use of MBE techniques for growth of IV-VI optoelectronic devices; for fabrication of integrated optical devices; and for the study of semiconductor surface and crystal physics. The final chapter examines a superlattice consisting of a periodic sequence of ultrathin p- and n-doped semiconductor layers, possibly with intrinsic layers in between. This monograph will be of interest to chemists, physicists, and crystallographers.
