Available in PDF, EPUB and Kindle. Book excerpt: These data sheets present a compilation of a wide range of electrical, optical and energy values for gallium phosphide and the gallium arsenidegallium phosphide system in bulk and film form. Electrical properties include lifetime and thermoelectric effects. Emission data have been broken down into the varied electron and photon emissions which result from application of energy in the electromagnetic spectrum. Energy data include energy bands, energy gap and energy levels for variously-doped gallium phosphide, as well as phonon assignments, effective mass tables and gyromagnetic ratios. The optical properties include absorption, reflection and refractive index. Magnetic data are included, as well asseveral bordering physical phenomena, such as Debye temperature, thermal emf and thermal conductivity. Each property is compiled over the widest possible range of parameters from references obtained in a thorough literature search. (Author).

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.

This book was released on 1980 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: System effects and data analysis for deep level transient spectroscopy (DLTS) have been examined and applied to study the deel levels in the GaAs-GaP system. Studies of typical DLTS systems using either the lock-in amplifier or the dual-channel boxcar averager are presented. The effects of non-zero gate width for the boxcar averager, phase angle adjustment for the lock-in amplifier, and response time of a typical commercial capacitance meter are investigated. Errors introduced in the measurements by these effects are calculated for typical cases. Measurements of gold level in silicon are presented, along with calculated corrections. We find the correction to be minimal in the boxcar-averager method, but significant in the lock-in amplifier approach. A DLTS system is described for measuring deep levels in diodes exhibiting large leakage currents. A capacitance bridge is used employing the diode to be tested along with a dummy diode of similar characteristics. The DLTS spectrum of a leaky GaAs planar diode is measured and compared to experimental results obtained with two standard DLTS systems . It is shown that measurements with the standard systems are impossible in certain temperature ranges because of overloading problems. The approach described here, however, gives the DLTS spectrum between 77 K and 300 K.
Book Synopsis Diffusion, Solubility, and Distribution Coefficient of Zinc in Gallium Arsenide and Gallium Phosphide by : Stanford University. Stanford Electronics Laboratories
Download or read book Diffusion, Solubility, and Distribution Coefficient of Zinc in Gallium Arsenide and Gallium Phosphide written by Stanford University. Stanford Electronics Laboratories and published by . This book was released on 1963 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiotracer Zn65 was vapor diffused in GaAs and GaP single crystals in closed, evacuated quartz ampoules. The solubilities and diffusion profiles were obtained over the temperature range 700 to 1100 C. The solubility data were analyzed by assuming Zn-GaAs and Zn-GaP to be binary systems and considering the transfer of neutral Zn from the liquid to the solid where some Zn atoms become ionized acceptors. The solubilities and distribution coefficients of Zn in these two semiconductor were calculated as functions of temperature up to the melting point of the solvents. The experimentally measured diffusion profile exhibit a steep front for Zn in GaAs above 700 C and for Zn in GaP above 900 C. Application of the Boltzmann-Matano method to these profiles shows that the diffusion coefficient is strongly concentration-dependent. A precise evaluation of this dependence was obtained from isoconcentration diffusions performed at a fixed temperature: 900 C for Zn in GaAs and 1000 C for Zn in GaP. (Author).
