    Raman studies of plasmon modes in a drifting two-dimensional electron gas (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 76 (1994), S. 1701-1705 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: We present the first Raman-scattering studies of the behavior of the intrasubband plasmon mode of a two-dimensional electron gas which is undergoing lateral drift in an applied electric field. The data clearly show the expected Doppler shifts of the modes traveling up- and downstream, together with the expected dependence on the wave vector, but at higher drift velocities, the expected linear shift is distorted because of electron heating effects.

    Magnetoresistance and magnetization in submicron ferromagnetic gratings (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 75 (1994), S. 5249-5256

    Topics: Physics
    Notes: A technique for engineering micron and submicron scale structures from magnetic films of transition metals has been developed using a combination of electron- and ion-beam lithography enabling high-quality arrays of submicron magnetic Fe wires to be fabricated. This process can be used to fabricate novel devices from a variety of metal combinations which would not be possible by the usual liftoff metallization method. The structure and magnetic properties are reported of an epitaxial 25 nm Fe(001)/GaAs(001) film and the wire gratings which are fabricated from it. The width of the wires in the grating is 0.5 μm for all structures studied, but the separation of each wire is varied in the range 0.5 to 16 μm. An artificially induced shape anisotropy field of around 1 kG, consistent with a magnetostatic calculation, was observed for all separations studied. The field dependence of the magneto-optic Kerr effect and magnetoresistance (MR) data is consistent with a twisted magnetization configuration across the width of the sample beneath saturation for transverse applied fields. In this case, the detailed form of the field dependence of the MR is strikingly modified from that observed in the continuous film and is consistent with coherent rotation of the magnetization.

    Oscillations in the frequencies and coupling strengths of two-dimensional plasmons induced by grating couplers (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 76 (1994), S. 5909-5915

    ISSN: 1089-7550

    Topics: Physics
    Notes: Direct optical coupling to the plasmon modes of a two-dimensional electron gas in a stratified semiconductor system requires an overlaid grating coupler. Plasmons can be excited with wave vectors equal to integer multiples of the grating wave vector, and the periodic screening by the grating splits these into two modes, symmetric and antisymmetric with respect to the grating profile. We present calculations of the dispersions and optical coupling strengths for several orders of both modes in a typical structure, and show that the splitting and coupling strengths of the higher order modes oscillate with varying grating mark fraction. These effects are discussed in terms of the oscillating field strengths and charge density profiles.

    GENERAL EQUILIBRIUM OF A REGIONAL ECONOMY WITH A FINANCIAL SECTOR–PART I: AN ACCOUNTING FRAMEWORK WITH BUDGET AND BALANCE SHEET LINKAGES (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of regional science 31 (1991), S. 0 
    Details
    ISSN: 1467-9787
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geography , Economics
    Notes: . An accounting framework is presented that can be used as a basis for a regional general equilibrium economic model that meaningfully incorporates both real and financial activity. The accounting framework describes a circular flow from regional income to credit base, and back to regional income, including the balance of payments identity. Both real market transactions and capital stock changes are explicitly recognized. Linkages between real activity flows and sectoral balance sheets are highlighted. Financial activity is recognized as a service, and all assets are assumed to be valued at market prices.

    TRAFFIC EXTERNALITIES AND SINGLE-FAMILY HOUSE PRICES (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of regional science 32 (1992), S. 0 
    Details
    ISSN: 1467-9787
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geography , Economics
    Notes: . This study is the first to lend empirical support to the common belief that traffic intensity affects property values. Using a standard hedonic pricing model, this paper investigates the price effects on housing of traffic within a neighborhood. Results using data on single-family housing transactions for two different locations in a medium-sized city show a substantial negative price effect of traffic externalities. The magnitude of the effect is shown to be location specific.

    GENERAL EQUILIBRIUM OF A REGIONAL ECONOMY WITH A FINANCIAL SECTOR–PART II: A SIMPLE BEHAVIORAL MODEL (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of regional science 32 (1992), S. 0 
    Details
    ISSN: 1467-9787
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geography , Economics
    Notes: . Simple behavioral assumptions are incorporated into an accounting framework that provides linked budget and balance sheets for sectors of a regional economy. A short-run Keynesian-type model is developed where quantities rather than prices adjust, and where regional prices and interest rates are equal to national levels. The analysis highlights the importance of the financial services sector as an active factor in regional growth. Consumer deposit and debt preferences, and limitations imposed on credit extension by the financial services sector can have important effects on the regional economy as evidenced by changes in the export multiplier.

    Evaluation of pulsed radiation effects in buried oxides by fast C-V measurements (1991)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 70 (1991), S. 4784-4789 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Fast C-V measurement techniques are utilized to simultaneously probe both upper and lower interfaces of silicon-on-insulator/separation by implantation of oxygen buried oxide capacitors following exposure to pulsed ionizing irradiation. In addition to the relatively stable radiation-induced positive charge, reverse annealing is observed from both Si-SiO2 interfaces over the 200 μs to 300 s post exposure interval; this behavior is consistent with electron detrapping within the oxide. The dependence of electron detrapping on dc annealing bias is attributed to field-enhanced emission effects.

    Gallium phosphide junctions with low leakage for energy conversion and near ultraviolet detectors (1991)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 69 (1991), S. 6500-6505 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: There is a need for semiconductor junctions with very low leakage for energy conversion from low level radioactive or radio-luminescent sources, and low noise blue-green photodiodes. We report the properties of two types of GaP junctions; a Schottky barrier of Pd on liquid phase epitaxy grown n-type GaP and a p+ over n junction grown by metal-organic chemical vapor deposition. Both types of junctions show very low leakage currents and good efficiency for power conversion from low level beta particles, x rays, and blue-green light.
