    Notes: Abstract This paper reports an effort to introduce high temperature superconductor (HTS) into the MEMS (microelectromechanical systems) field, to develop fabrication procedures suitable for HTS, and using them to fabricate a prototype superconductor microsensor for magnetic field detection. The prototype device fabricated is a sensor based on the giant magnetoresistivity of a high temperature superconductor around its critical temperature. It was fabricated using optical lithography and electrodeposition of Tl1Ba2Ca2Cu3Ox (Tl-1223) type high T C superconductors. The test results of the prototype sensor fabricated show that the prototype sensor has a very high magnetoresistivity at medium to strong magnetic field strength and low magnetoresistivity at weak magnetic field. Our work suggests that in order to develop a high precision magnetic sensor for the detection of very weak magnetic fields, other HTS materials with less flux pinning effect and more weak links need to be pursued. The MEMS fabrication process developed is simple, repeatable, and applicable to microfabrication of other types of superconductor devices.

    Notes: Summary ¶ Brain stem epidermoid cysts are extremely rare. We describe an unusual case of prepontine epidermoid cyst with a large part of the tumour insinuating itself into the pons. Microsurgical total excision of tumour was done without producing any new neurological deficits. Cases reported in the literature either had high mortality/morbidity or were only subtotally removed. Relevant literature is reviewed.

    Heterojunction CdS/CdTe solar cells based on electrodeposited p-CdTe thin films: Fabrication and characterization (1985)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The electrodeposition technique previously developed by the present authors for in situ growth of p-type CdTe thin films, has been further improved using As as an acceptor dopant. Photovoltaic-quality films were grown on conducting glass and Mo substrates and characterized by scanning electron microscopy, electron probe microanalyses, and Auger electron spectroscopy. These films were subsequently utilized in the construction of inverted photovoltaic cell structures comprising the n-CdS/p-CdTe heterojunction. Efficiencies approaching the 5% level (AM1 insolation) have been obtained thus far on small-area (∼0.20 cm2) devices.

    Thin-film CuIn1−xGaxSe2 photovoltaic cells from solution-based precursor layers (1999)

    Notes: We have fabricated 15.4% and 12.4% efficient thin-film CuIn1−xGaxSe2 (CIGS)-based photovoltaic devices from solution-based electrodeposited (ED) and electroless-deposited (EL) precursors. As-deposited precursors are Cu-rich CIGS. Additional In, Ga, and Se are added to the ED and EL precursor films by physical vapor deposition (PVD) to adjust the final semiconductor film composition to CuIn1−xGaxSe2. The ED and EL device parameters are compared with those of a 17.7% PVD device. The tools used for comparison are current voltage, capacitance voltage, and spectral response characteristics. © 1999 American Institute of Physics.

    Notes: Summary Let X t∶t≧0 be an ergodic stationary Markov process on a state space S. If  is its infinitesimal generator on L 2(S, dm), where m is the invariant probability measure, then it is shown that for all f in the range of $$\hat A,n^{ - {1 \mathord{\left/ {\vphantom {1 2}} \right. \kern-\nulldelimiterspace} 2}} \int\limits_0^{nt} {f(X_s ){\text{ }}ds{\text{ }}(t\underline{\underline 〉 } } 0)$$ converges in distribution to the Wiener measure with zero drift and variance parameter σ 2 =−2〈f, g〉=−2〈Âg, g〉 where g is some element in the domain of  such that Âg=f (Theorem 2.1). Positivity of σ 2 is proved for nonconstant f under fairly general conditions, and the range of  is shown to be dense in 1⊥. A functional law of the iterated logarithm is proved when the (2+δ)th moment of f in the range of  is finite for some δ〉0 (Theorem 2.7(a)). Under the additional condition of convergence in norm of the transition probability p(t, x, d y) to m(dy) as t → ∞, for each x, the above results hold when the process starts away from equilibrium (Theorems 2.6, 2.7 (b)). Applications to diffusions are discussed in some detail.

    Thick-Film Processing for Tl-Oxide Wire and Tape (1998)
    Springer
    Journal of superconductivity 11 (1998), S. 173-180

    Notes: Abstract Thick-film processing techniques such as electrodeposition, electrophoresis, spray pyrolysis, and ink spraying offer promising and economic (〈$10/kAm) approaches for fabricating high-temperature superconducting (HTS) wire or tape for the Tl-oxide superconductors. The performance of the Tl system exceeds that for the Bi-oxides and offers easier fabrication than YBCO. Scale up, however, may be difficult because of the need for open tape conductors with aligned microstructures. The Tl-oxides, moreover, offer the potential for operation at 77K in practical magnetic fields of 3-5 T, which is supported by measurements on the irreversibility behavior of the Tl-1223 single layer compound with Pb, Bi, and Sr substitution. Recent advances in the development of biaxial textured electrodeposited films on Ag coated single crystal substrates are discussed. This paper will review the merits for a near-term Tl-oxide based conductor for use in HTS electric power applications, currently under development, such as the transformer and transmission cable. Recent results for the buffer layer development that would provide an oriented ceramic layer or template on a flexible textured nickel substrate utilizing the “RABiTS” substrates developed by ORNL will then be discussed with a projection for the cost of a “long length” thick-film process using electrodeposition.
