Book excerpt: Further, an improved physical model for base push-out effect based on a high field mobility model of GaAs has been established which included velocity modulation effect and non uniform electron concentration profile. Critical electric field profile in the collector is compared with a device simulation results and impact of temperature and base-collector voltage on Kirk effect discussed. A large signal compact model implementing these expressions could predict both isothermal and the dynamic behavior of a 2x20 um2 device accurately in the high collector voltage high collector current region.
Book Synopsis Growth and Characterization of Indium Gallium Phosphide on Gallium Arsenide by Gas Source Molecular Beam Epitaxy System and Its Applications to Heterostructures by : Dhrubes Biswas
Download or read book Growth and Characterization of Indium Gallium Phosphide on Gallium Arsenide by Gas Source Molecular Beam Epitaxy System and Its Applications to Heterostructures written by Dhrubes Biswas and published by . This book was released on 1993 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: InGaP/GaAs system presents an attractive alternative to GaAs/AlGaAs system for heterojunction devices because of its unique heterojunction properties, wide band gap of about 1.90 eV for the lattice matched composition and absence of oxidation problems typical for AlGaAs. However, the growth of InGaP requires the use of phosphine, which necessitated the use of Gas Source Molecular Beam Epitaxy (GSMBE). The gases involved are very hazardous, extremely toxic, highly inflammable and explosive at elevated temperatures. Adequate care has been taken for the safe use of these gases so that this attractive technique is properly utilized. The GSMBE system is equipped with a central alarm command system with audio-visual alarms for a variety of monitored conditions and interlocks for automatic shutdown. Samples studied were grown on (100) GaAs substrates under various growth conditions. Reproducible growth conditions have been established with respect to optimisation of pressure and temperature so as to achieve good material properties. Structural characterization using X ray has been carried out for the determination of material composition and evaluation of crystal quality. Very narrow full width at half maxima values indicated good crystal quality. Additionally, cross-sectional TEM has shown smooth heterointerface. Subsequent to this, good hall mobility at room temperature and at 77K, confirmed the material quality. Photoluminescence has been utilized for the evaluation of the E$\sb0$ gap. The PL exhibited very narrow full width at half maxima for lattice matched composition. Apart from evaluation of the E$\sb1$ gap, spectroscopic ellipsometry has been used to investigate the compositional dependence of the E$\sb1$ gap (and its broadening). P-type modulation doped heterostructures has been implemented using InGaP/GaAs, demonstrating two dimensional hole gas (2DHG) with good p-type hole mobilities measured from room temperature up to very low temperatures. The approximate constant value of mobility in the low temperature region strongly confirms the presence of 2DHG. A simple model has been formulated for the estimation of valence band discontinuity from the measured 2DHG data at cryogenic temperatures. Heterostructure Bipolar Transistor has been demonstrated using InGaP/GaAs system with the realisation of good current gain and low offset voltages. The double heterostructure bipolar transistor showed even smaller offset voltages. The classical V$\sb{CE}$ versus I$\sb{c}$ plots and gummel plots for the devices shows an ideality factor close to unity for I$\sb{c}$ and other usual characteristic features.

Book Synopsis Dilute Nitride Semiconductors by : Mohamed Henini
Download or read book Dilute Nitride Semiconductors written by Mohamed Henini and published by Elsevier. This book was released on 2004-12-15 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains full account of the advances made in the dilute nitrides, providing an excellent starting point for workers entering the field. It gives the reader easier access and better evaluation of future trends, Conveying important results and current ideas. Includes a generous list of references at the end of each chapter, providing a useful reference to the III-V-N based semiconductors research community. The high speed lasers operating at wavelength of 1.3 μm and 1.55 μm are very important light sources in optical communications since the optical fiber used as a transport media of light has dispersion and attenuation minima, respectively, at these wavelengths. These long wavelengths are exclusively made of InP-based material InGaAsP/InP. However, there are several problems with this material system. Therefore, there has been considerable effort for many years to fabricate long wavelength laser structures on other substrates, especially GaAs. The manufacturing costs of GaAs-based components are lower and the processing techniques are well developed. In 1996 a novel quaternary material GaInAsN was proposed which could avoid several problems with the existing technology of long wavelength lasers. In this book, several leaders in the field of dilute nitrides will cover the growth and processing, experimental characterization, theoretical understanding, and device design and fabrication of this recently developed class of semiconductor alloys. They will review their current status of research and development. Dilute Nitrides (III-N-V) Semiconductors: Physics and Technology organises the most current available data, providing a ready source of information on a wide range of topics, making this book essential reading for all post graduate students, researchers and practitioners in the fields of Semiconductors and Optoelectronics Contains full account of the advances made in the dilute nitrides, providing an excellent starting point for workers entering the field Gives the reader easier access and better evaluation of future trends, conveying important results and current ideas Includes a generous list of references at the end of each chapter, providing a useful reference to the III-V-N based semiconductors research community

Book Synopsis Millimeter-Wave Low Noise Amplifiers by : Mladen Božanić
Download or read book Millimeter-Wave Low Noise Amplifiers written by Mladen Božanić and published by Springer. This book was released on 2017-11-30 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first standalone book that combines research into low-noise amplifiers (LNAs) with research into millimeter-wave circuits. In compiling this book, the authors have set two research objectives. The first is to bring together the research context behind millimeter-wave circuit operation and the theory of low-noise amplification. The second is to present new research in this multi-disciplinary field by dividing the common LNA configurations and typical specifications into subsystems, which are then optimized separately to suggest improvements in the current state-of-the-art designs. To achieve the second research objective, the state-of-the-art LNA configurations are discussed and the weaknesses of state-of the art configurations are considered, thus identifying research gaps. Such research gaps, among others, point towards optimization – at a systems and microelectronics level. Optimization topics include the influence of short wavelength, layout and crosstalk on LNA performance. Advanced fabrication technologies used to decrease the parasitics of passive and active devices are also explored, together with packaging technologies such as silicon-on-chip and silicon-on-package, which are proposed as alternatives to traditional IC implementation. This research outcome builds through innovation. Innovative ideas for LNA construction are explored, and alternative design methodologies are deployed, including LNA/antenna co-design or utilization of the electronic design automation in the research flow. The book also offers the authors’ proposal for streamlined automated LNA design flow, which focuses on LNA as a collection of highly optimized subsystems.
