    Notes: The quality of large semiconductor crystals grown from the melt for use in electronic and optoelectronic devices is strongly influenced by the intricate coupling of heat and mass transfer and melt flow in growth systems. This paper reviews the present state of understanding of these processes starting from the simplest descriptions of solidification processes to detailed numerical calculations needed for quantitative modeling of processing with solidification. Descriptions of models for the vertical Bridgman-Stockbarger and Czochralski crystal growth techniques are included as examples of the level of understanding of industrially important methods.

    Direct evidence for antifreeze glycoprotein adsorption onto an ice surface (1985)
    New York : Wiley-Blackwell
    Biopolymers 24 (1985), S. 1265-1270

    ISSN: 0006-3525

    Topics: Chemistry and Pharmacology
    Notes: Aqueous solutions of antifreeze glycoproteins (AFGP) exhibit hysteresis between the freezing and melting temperatures. Several recent studies on the mechanism of function of this protein system suggest that a likely model is for the antifreeze molecules to be adsorbed onto the surface of the crystals. However, direct proof of the presence of adsorbed AFGP has eluded previous researchers. In the present study, enhanced surface second-harmonic generation (SSHG) was observed in the presence of an active AFGP solution in contact with a pure single crystal of ice. The enhancement of SSHG is a positive indication that active AFGP molecules adsorb to the surface of ice crystals.

    A measurement of the rate of the reaction N + H + M → NH + M (1973)

    Notes: The combination reaction between N and H atoms has been studied in a flow system by mixing H atoms produced by thermal dissociation of H2 with active nitrogen produced by a microwave discharge. Relative N atom concentrations were determined from the intensity of the yellow nitrogen afterglow. Absolute N and H atom concentrations were measured by EPR absorption spectroscopy. Absolute N atom concentrations were also determined by titration with NO. Upper and lower limits of 6.4 ± 1.5 × 10-32 and 3.1 ± 1.0 × 10-32 cm6 molecule-2 sec-1 were determined for the rate constant.

    Petrov-Galerkin methods for natural convection in directional solidification of binary alloys (1987)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: A Petrov-Galerkin finite element method is presented for calculation of the steady, axisymmetric thermosolutal convection and interface morphology in a model for vertical Bridgman crystal growth of nondilute binary alloys. The Petrov-Galerkin method is based on the formulation for biquadratic elements developed by Heinrich and Zienkiewicz and is introduced into the calculation of the velocity, temperature and concentration fields. The algebraic system is solved simultaneously for the field variables and interface shape by Newton's method. The results of the Petrov-Galerkin method are compared critically with those of Galerkin's method using the same finite element grids. Significant improvements in accuracy are found with the Petrov-Galerkin method only when the mesh is refined and when the formulation of the residual equations is modified to account for the mixed boundary conditions that arise at the solidification interface. Calculations for alloys with stable and unstable solute gradients show the occurrence of classical flow transitions and morphological instabilities in the solidification system.

    Third-order resonance effects and the nonlinear stability of drop oscillations (1987)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: The three-dimensional nonlinear oscillations of an isolated, inviscid drop with surface tension are studied by a multiple timescale analysis and pre-averaging applied to the variational principle for the appropriate Lagrangian. Amplitude equations are derived which describe the generic cubic resonance caused by the spatial degeneracy of the eigenfrequencies of the linear normal modes. This resonant coupling leads to the instability of the finite amplitude axisymmetric oscillations to small nonaxisymmetric perturbations, as is demonstrated here for the three- and four-lobed normal modes. Solutions to the interaction equations that describe finite amplitude, nonaxisymmetric traveling-wave solutions are also obtained and their stability is investigated. A nongeneric cubic resonance between the two-lobed and four-lobed oscillatory modes leads to quasi-periodic motions.
