Test Structures for Referencing Electrical Linewidth Measurements to Silicon Lattice Parameters Using HRTEM

May 1, 2003
Author(s)
Richard A. Allen, B A. am Ende, Michael W. Cresswell, Christine E. Murabito, T J. Headley, William F. Guthrie, Loren W. Linholm, Colleen E. Hood, E. Hal Bogardus
A technique has been developed to determine the linewidths of the features of a prototype reference material for the calibration of CD (Critical-Dimension) metrology instruments. The reference features are fabricated in mono-crystalline-silicon with the

The Alternating Direction Implicit (ADI) Formulation of the Finite-Difference Time-Domain (FDTD) Method: Algorithm and Material Dispersion Implementation

May 1, 2003
Author(s)
Shawn W. Staker, Christopher L. Holloway, Alpesh Bhobe, Melinda Piket-May, Tobin A. Driscoll
The ADI-FDTD technique is an unconditionally stable time-domain numerical scheme, allowing the Δ}t time step to be increased beyond the Courant-Friedrichs-Lewy (CFL) limit. Execution time of a simulation is inversely proportional to Δ}t, and as such

The Customer Speaks: How the Users See the NIST Research Library

May 1, 2003
Author(s)
Barbara P. Silcox, P J. Deutsch
The Research Advisory Committee (RAC) at the National Institute of Standards and Technology (NIST) in its 2000 Annual Report to the NIST Director expressed concern that the NIST Research Library would not be able to meet the research needs of the

The ebXML Test Framework and the Challenges of B2B Testing

May 1, 2003
Author(s)
J Durand, Michael J. Kass, P Wenzel
Testing tools for Conformance and Interoperability are emerging as a key technology for enabling and maintaining interoperability between e-Business partners. Verifying adherence to a common standard (conformance) is just the first step. In addition, it is

The Effect of Delay Mismatch in MPLS Networks Using 1+1 Protection

May 1, 2003
Author(s)
David W. Griffith, Sanghun Lee, L Krivulina
High-capacity optical-fiber backbone networks protect information flows belonging to their premium customers by routing two copies of the customer's data over disjoint paths. This scheme, known as 1+1 protection, ensures that the customer will experience

The Eleventh Text REtrieval Conference (TREC-11)

May 1, 2003
Author(s)
Ellen M. Voorhees, Donna K. Harman
The Eleventh Text Retrieval Conference was held in Gaithersburg, Maryland, November 19-22, 2002. TREC 2002 is the latest in a series of workshops designed to foster research in information retrieval and related tasks. This year's conference consisted of

The IEEE Standard on Transitions, Pulses, and Related Waveforms, Std-181

May 1, 2003
Author(s)
Nicholas Paulter, Donald R. Larson, Jerome J. Blair
The IEEE has revised the now withdrawn IEEE standards on pulse techniques and definitions. This revision includes adding and deleting definitions, clarifying existing definitions, providing examples of different waveform types, updating text to reflect

Three Dimensional Phase Field Modeling of Binary Eutectics

May 1, 2003
Author(s)
D J. Lewis, William J. Boettinger, James A. Warren
A multi-phase field model was used to study the three-dimensional dynamics of morphology evolution in binary eutectics. Performing the calculations in three dimensions enables the study of the transition from rod-like to lamellar morphology and the study

Tuning the Response of Magnetic Suspensions

May 1, 2003
Author(s)
M. Chen, L Sun, John E. Bonevich, Daniel H. Reich, C L. Chien, P C. Searson
The magnetic properties of multilayer ferromagnetic/nonmagnetic (FM/NM) nanowires can be tailored by controlling the composition and length of the FM and NM segments. Manipulation of properties such as the magnetic easy axis, Curie temperature (TC)

Ultrafast Dynamics of Gold-Based Nanocomposite Materials

May 1, 2003
Author(s)
Joseph S. Melinger, V D. Kleiman, D McMorrow, Franziska Grohn, Barry J. Bauer, Eric J. Amis
The ultrafast electron dynamics are investigated for small ((2.5 4.0) nm average diameter) Au nanoparticles contained in two different types of organic-inorganic nanocomposites. In one case, an aqueous solution contains Au nanoparticles embedded inside

Updated NIST Photomask Linewidth Standard

May 1, 2003
Author(s)
J Pedulla, James E. Potzick, Michael T. Stocker
NIST is preparing to issue the next generation in its line of binary photomask linewidth standards. Called SRM 2059, it was developed for calibrating microscopes used to measure linewidths on photomasks, and consists of antireflecting chrome line and space

Visualization of Structural Steel Product Models

May 1, 2003
Author(s)
Robert R. Lipman, K A. Reed
A visual interface has been developed to provide a means for users to visualize the steel structure represented by a CIMsteel Integration Standards Release 2 (CIS2) file. Using a web-accessible translator, objects in a user's CIS2 file are mapped to

Vulnerabilities in Quantum Key Distribution Protocols

May 1, 2003
Author(s)
David R. Kuhn
Recently proposed quantum key distribution protocols are shown to be vulnerable to a classic man-in-the-middle attack using entangled pairs created by Eve. The attack could be applied to any protocol that relies on manipulation and return of entangled

Counting Errors in a Voltage-Biased Electron Pump

April 30, 2003
Author(s)
Xavier Jehl, Mark W. Keller, Richard L. Kautz, Joe Aumentado, John M. Martinis
We have measured the counting errors of a 7-junction electron pump when charge is pumped against a voltage difference. At voltages above about 50 υV, we find that the errors increase exponentially with both pump voltage and temperature, in agreement with

Quantitative Analysis and Characterization of DNA Immobilized on Gold

April 30, 2003
Author(s)
D Y. Petrovykh, H Y. Kimura-Suda, L J. Whitman, Michael J. Tarlov
We describe the complementary use of x-ray photoelectron spectroscopy (XPS) and fourier transform infrared (FTIR) spectroscopy to quantitatively characterize the immobilization of thiolated poly(dT)25 single-stranded DNA (ssDNA) on gold. When electron
