  • A parallel/vector Monte Carlo MESFET model for shared memory machines

    Creator:
    Huster, Carl R.
    Abstract:
    The parallelization and vectorization of Monte Carlo algorithms for modelling charge transport in semiconductor devices are considered. The standard ensemble Monte Carlo simulation of a three parabolic band model for GaAs is first presented as partial verification of the simulation. The model includes scattering due to acoustic, polar-optical and intervalley...

  • Analysis and control of power systems using orthogonal expansions

    Creator:
    Fernandes, Stephen Ronald
    Abstract:
    In recent years, considerable attention has been focused on the application of orthogonal expansions to system analysis, parameter identification, model reduction and control system design. However, little research has been done in applying their useful properties to Power System analysis and control. This research attempts to make some inroads in...

  • Two dimensional numerical simulation of a non-isothermal GaAs MESFET

    Creator:
    Lin, Angela A.
    Abstract:
    The low thermal conductivity of gallium arsenide compared to silicon results in self-heating effects in GaAs MESFETs that limit the electrical performance of such devices for high power applications. To date, analytical thermal models of self heating in GaAs MESFETs are based on the assumption of a uniformly heated channel....

  • Growth, fabrication and testing of pseudomorphic P-channel GaAs/InGaAs/AlGaAs MODFETS

    Creator:
    Schulte, Donald W.
    Abstract:
    This thesis reports on the growth and characterization of p-type pseudomorphic A1GaAs /InGaAs /GaAs modulation doped field effect transistor (MODFET) structures. A series of different p-type MODFET structures were grown with a systematic variation of the indium mole fraction and quantum well width of the InGaAs channel region. Extensive characterization...

  • Fabrication and characterization of modulation doped field effect transistors for quantum waveguide structures

    Creator:
    Yindeepol, Wipawan, 1960-
    Abstract:
    Split and normal gate A1GaAs /GaAs MODFETs were fabricated along with the ohmic test structures and the Hall bar geometries. The DC characteristics of normal gate transistors were evaluated at room temperature and at 77K and the threshold voltages were extracted from the measurements and compared to the theoretical results....

  • Hot electron transport and relaxation in quantum wells and superlattices

    Creator:
    Lary, Jenifer Edith
    Abstract:
    Electron transport and relaxation may be substantially different in low-dimensional systems compared to that observed in bulk material. In the present work, Monte Carlo models are used for the solution to the Boltzmann transport equation, with scattering rates calculated quantum mechanically for superlattice and quantum wells. Carrier relaxation following optical...

  • Monte Carlo device modeling applications on parallel computers

    Creator:
    Pennathur, Shankar S.
    Abstract:
    One of the ways of countering the ever increasing computational requirements in the simulation and modeling of electrical and electromagnetic devices and phenomena, is the development of simulation and modeling tools on parallel computing platforms. In this thesis, a previously developed Monte Carlo parallel device simulator is utilized, enhanced, and...

    Creator:
    Chang, Chujyh
    Abstract:
    Different gate length (0.5 μm 16 μm) Al GaAs/GaAs and AIGaAs /InGaAs High Electron Mobility Transistors were electrically characterized in order to compare the room temperature DC device performance with one-dimensional device models. Model parameters such as the channel mobility and source/drain series resistances are extracted from independent measurement of...

  • Analog integrated circuit design using GaAs C-HFETs

    Creator:
    Gupta, Rakhee
    Abstract:
    Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...
