Optical properties of boron carbide (B5C) thin films fabricated by plasma-enhanced chemical-vapor deposition

Variable angle of incidence spectroscopic ellipsometry was used to determine the optical constants near the band edge of boron carbide (B5C) thin films deposited on glass and n-type Si(111) via plasma-enhanced chemical-vapor deposition. The index of refraction n, the extinction coefficient k, and the absorption coefficient are reported in the photon energy spectrum between 1.24 and 4 eV. Ellipsometry analysis of B5C films on silicon indicates a graded material, while the optical constants of B5C on glass are homogeneous. Line shape analyses of absorption data for the films on glass indicate an indirect transition at approximately 0.75 eV and a direct transition at about 1.5 eV. ©1996 American Institute of Physics.

Review of The Bible at Qumran: Text, Shape, and Interpretation, edited by Peter W. Flint

Review of The Bible at Qumran: Text, Shape, and Interpretation, edited by Peter W. Flint. Studies in the Dead Sea Scrolls and Related Literature. Grand Rapids, MI: Eerdmans, 2001. Pp. xv + 266. Price: $22.00. ISBN 0-8028-4630-0. This volume is another contribution to the Eerdmans series Studies in the Dead Sea Scrolls and Related Literature. The essays are loosely gathered around the topic "The Bible at Qumran," and the editor has divided the articles into two groups. Part 1, "The Scriptures, the Canon, and the Scrolls," includes articles by J.A. Sanders, B.W. Waltke, E. Ulrich, C.A. Evans, and the editor, P.W. Flint. The contributors to Part 2, "Biblical Interpretation and the Dead Sea Scrolls," are J.C. VanderKam, C.A. Evans, J.E. Bowley, J.M. Scott, M.G. Abegg, and R.W. Wall. Unlike other volumes of collected essays in this series, which have highlighted the work of a single author or published the proceedings of a particular conference, this collection has a more disparate origin. Some contributions were given as papers at the Dead Sea Scrolls Institute of Trinity Western University (Bowley, Ulrich, VanderKam and Wall), one (Waltke) is reprinted from The New International Dictionary of Old Testament Theology and Exegesis (Grand Rapids: Zondervan, 1997), and the rest (Abegg, Evans, Flint, Sanders and Scott) were invited for the volume.
