    Differential amplitude contrast imaging in the scanning optical microscope (1983)
    Springer
    Applied physics 32 (1983), S. 187-191 
    Details
    ISSN: 1432-0649
    Keywords: 42.80
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A split detector is used in a scanning optical microscope to produce high-quality differential amplitude contrast images. A slight lateral offset in the detector position is shown to introduce information about object height variations to the image. These results are compared with images obtained by electrical differentiation.

    Higher diffracted orders in a BSO crystal: An experimental study of transients (1989)
    Springer
    Applied physics 49 (1989), S. 431-433 
    Details
    ISSN: 1432-0649
    Keywords: 42.40 ; 42.65 ; 42.80
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The emergence of higher diffracted orders when a slightly wedged BSO crystal is illuminated by a single coherent beam is studied with input power and applied voltage as parameters. It is shown that the power spreads gradually towards the higher orders and that the temporal variation of the power in each beam is qualitatively the same as in the case of two-wave interaction.

    Three-dimensional surface measurement using the confocal scanning microscope (1982)
    Springer
    Applied physics 27 (1982), S. 211-213 
    Details
    ISSN: 1432-0649
    Keywords: 06 ; 42.80
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The use of the depth discriminination property of the confocal scanning microscope for surface profiling has been adapted to provide a method of high-resolution three-dimensional surface profilometry. Measurements on a semiconductor specimen demonstrate the technique; depth variations of the order of 0.1 μm are clearly resolved.

    Ab initio factorized LCAO calculation of the electronic structure of α-SiO2 (1992)

    Notes: We report on the results of calculations of the electronic structure of α-quartz that were made using the first principles, factorized linear combination of atomic orbitals method. Results were obtained for the primitive 9-atom, and orthorhombic 18- and 72-atom unit cells. Application of this method to the calculation of the electronic structure of the neutral oxygen vacancy in α-quartz is discussed and results obtained using a 72-atom unit cell are given. © 1992 John Wiley & Sons, Inc.

    Ab initio factorized LCAO calculations of the electronic band structure of ZnSe, ZnS, and the (ZnSe )1(ZnS)1 strained-layer superlattice (1992)

    Notes: We report on the results of electronic band structure calculations of bulk ZnSe, bulk ZnS, and the (ZnSe)1(ZnS)1 strained-layer superlattice (SLS) using the ab initio factorized linear combination of atomic orbitals method. The bulk calculations were done using the standard primitive nonrectangular 2-atom zincblende unit cell, while the SLS calculation was done using a primitive tetragonal 4-atom unit cell modeled from the CuAu I structure. The analytic fit to the SLS crystalline potential was determined by using the nonlinear coefficients from the bulk fits. The CPU time saved by factorizing the energy matrix integrals and using a rectangular unit cell is discussed. © 1992 John Wiley & Sons, Inc.

    Ab initioSCF calculations on Mn-related defects in CaF2 (1992)
    New York, NY : Wiley-Blackwell
    International Journal of Quantum Chemistry 44 (1992), S. 673-686

    ISSN: 0020-7608

    Notes: We report on the progress in a study to determine the structure of radiation-induced Mn defect complexes in CaF2. The purpose of this study is to correlate the calculated transition energies with those measured experimentally and to determine what effect the inclusion of the external lattice field has on these transitions. Unrestricted open shell Hartree-Fock Self-Consistent Field (UHF) calculations were performed on the unperturbed F-center [Ca4F6Vac]1+ S = 1/2, the unperturbed Mn2+ center [MnF8]6- S = 5/2, S = 3/2 and the Mn2+ perturbed F-center [Mn2Ca2F6Vac]1+ S = 11/2, S = 9/2 defect clusters. A method by which the effects of the external lattice field may be incorporated in the SCF procedure is developed and used in these calculations. Several transition energies are calculated and Mulliken population results for these clusters are presented and discussed. © 1992 John Wiley & Sons, Inc.
