    Low-energy proton detection by Pd metal-insulator-semiconductor diodes (1988)

    Notes: It has been discovered that palladium-gated metal-insulator-silicon Schottky barrier diodes are very sensitive to fluxes of energetic protons in high vacuum. Data on the dosimetric response of the diodes to energetic protons are presented, along with data on the subsequent decay in the induced signal. A model for the response is developed, based on the response of similar structures to partial pressures of molecular hydrogen. The model involves adsorption sites at both the external Pd surface and the interface between Pd and SiO2, as well as known H absorption properties of bulk Pd. The sensitivity at 300 K of our diodes is about 109 protons (1011 cm−2). The inventory of protons stored in the bulk Pd, the surface, and at the interface indicates that the areal site density for the surface and interface is about 1015 cm−2.

    Hydrogen particle diagnostic based on Pd-MOS diode arrays (1988)

    Notes: The reverse-bias current through a Pd-MOS diode changes when hydrogen is present at the diode interface and this effect provides the bias for a solid-state detector to monitor the flux and energy of hydrogen particles emanating from a beam or plasma. The addition of a coating atop the Pd forms a high-pass energy filter and an array of coated Pd-MOS diodes can function as a compact, hydrogen-specific, energy spectrometer. The response characteristics of an Au-coated Pd-MOS diode array have been measured using a low-energy hydrogen ion source. The array has several desirable characteristics for energetic hydrogen detection. Its response is dosimetric, it discriminates between hydrogen irradiations at different energies, and it can be regenerated by heating briefly to 100–200 °C. These properties make Pd-MOS diode arrays attractive candidates for remote plasma-edge flux and energy monitors in fusion devices.

    Deep states in silicon-on-insulator substrates prepared by oxygen implantation using current deep level transient spectroscopy (1988)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 53 (1988), S. 871-873 
    Details
    ISSN: 1077-3118

    Topics: Physics
    Notes: Current deep level transient spectroscopy was applied using enhancement n-channel metal-oxide-semiconductor field-effect transistors fabricated in silicon-on-insulator substrates (prepared by oxygen implantation) to study the deep levels existing in the substrates. The current transients are not affected by the large series resistances which affect the measurement of capacitance transients on thin films. For the transistors used in this work a hole trap was found with energy ET=0.63 eV above the valence-band edge. The concentration and capture cross section of this state were estimated to be 1014 cm−3 and 10−16 cm2, respectively.

    Sequential tunneling due to intersubband scattering in double-barrier resonant tunneling devices (1988)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 52 (1988), S. 212-214

    Topics: Physics
    Notes: Magnetoquantum oscillations in the tunnel current of double-barrier n-GaAs/(AlGa)As/GaAs/(AlGa)As/GaAs resonant tunneling devices reveal evidence of sequential tunneling in the voltage range corresponding to the resonance when electrons tunnel into the second subband of the GaAs quantum well. The sequential tunneling arises from intersubband scattering between two quasi-bound states of the well. Near this resonance, the charge buildup in the well can be estimated from the magnetoquantum oscillations.

    Aerosol flow reactor production of fine Y1Ba2Cu3O7 powder: Fabrication of superconducting ceramics (1988)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 52 (1988), S. 1622-1624 
    Details
    ISSN: 1077-3118

    Topics: Physics
    Notes: An aerosol flow reactor operating at 900–1000 °C is used to prepare high-purity Y1Ba2Cu3O7 powders with a uniform chemical composition and a submicron to micron average particle size by thermally decomposing aerosol droplets of a solution consisting of the nitrate salts of Y, Ba, and Cu in a 1:2:3 ratio. The powders were at least 99% reacted based on thermogravimetric analysis, and the x-ray diffraction pattern is essentially that of Y1Ba2Cu3O7. Magnetic susceptibility measurements showed the powders to be superconducting with a transition at 90 K even for average reactor residence times as short as 20 s. Sintering cold-pressed pellets between 900 and 1000 °C provides dense, fine grained (average size on the order of 1 μm) superconducting ceramics with sharp 90 K transitions. The grain size and shape of a final sintered part could be varied depending on powder production, processing, and sintering conditions.
