Molecular Beam Epitaxial Growth of High-Quality GaN Nanocolumns

Author(s)
J E. Van Nostrand, J. E. Averett, R Cortez, J. Boeckl, C Stutz, Norman Sanford, Albert Davydov, M M. Maska
Vertically oriented gallium nitride GaN nanocolumns (NCs) approximately 90±10 nm wide and 0.75 microns tall were grown by plasma-assisted molecular beam epitaxy...

Fabrication of Prototype Imaging Arrays for SCUBA-2

Author(s)
Gene C. Hilton, James A. Beall, W.Bertrand (Randy) Doriese, William Duncan, S. L. Ferreira, Kent D. Irwin, Carl D. Reintsema, Joel Ullom, Leila R. Vale, Yizi Xu, Barry L. Zink, William Parkes, Andrew S. Bunting, Camilla Dunare, Alan Gundlach, T. Stevenson, Anthony Walton, Eric Schulte, Elizabeth Corrales, Joseph P. Sienicki, Dan Bintley, Peter Ade, Rashmi Sudiwala, Adam L. Woodcraft, Mark Halpern, Wayne Holland, Damian Audley, Michael MacIntosh
Prototype imaging sub-arrays for SCUBA-2 (the Sub-millimeter Common-User Bolometer Array) have been fabricated and tested. The pixel count (1280) of these wafer...

Cryptographic Primitives Can Be Fragile

Author(s)
Rene C. Peralta
We show that a well-known coin-flipping protocol is breakable in the sense that one of the parties can pre-determine the result of the coin-flip. The way in...

Microwave Spectrum and Structure of Methyl Phosphonic Difluoride

Author(s)
R D. Suenram, Francis J. Lovas, David F. Plusquellic, M W. Elizy, J M. Lochner, J O. Jensen, A C. Samuels
The rotational spectrum of methyl phosphonic difluoride has been reinvestigated using a pulsed-molecular-beam Fabry-Perot cavity microwave spectrometer. The...

Phase-Field Modeling of Solidification Under Stress

Author(s)
Julia Slutsker, K Thornton, Alexander Roytburd, James A. Warren, Geoffrey B. McFadden, P W. Voorhees
A phase-field model that includes the stress field during non-isothermal phase transformation of a single-vomponent system has been developed. The model has...

Fiber Deflection Probe for Small Hole Metrology

Author(s)
Balasubramanian Muralikrishnan, Jack A. Stone Jr., John R. Stoup
This paper presents the development of a new probing method for Coordinate Measuring Machines (CMM) to inspect diameter and form of small holes. The technique...

Relaxation Effects in Small Critical Nozzles

Author(s)
Aaron N. Johnson, C L. Merkle, Michael R. Moldover, John D. Wright
We computed the flow of four gases (He, N 2, CO 2, and SF 6) through a critical nozzle by augmenting traditional computational fluid dynamics (CFD) with a rate...

Radiative Decay Mode of the Free Neutron
