Photoemission Threshold Spectroscopy: MOS Band alignments

April 7, 2011
Author(s)
Nhan V. Nguyen
In this talk I will 1) briefly review SED’s history of the optical thin metrology project, 2) describe the principle of internal photoemission (IPE) and the applications to determine the band alignments of metal-oxide-semiconductor structures, and 3)

Salient Local 3D Features for 3D Shape Retrieval

April 7, 2011
Author(s)
Afzal A. Godil, Asim Wagan
In this paper we describe a new formulation for the 3D salient local features based on the voxel grid inspired by the Scale Invariant Feature Transform (SIFT). We use it to identify the salient keypoints (invariant points) on a 3D voxelized model and

SHREC11 Track: Shape Retrieval on Non-rigid 3D Watertight Meshes

April 7, 2011
Author(s)
Zhouhui Lian, Afzal A. Godil
Non-rigid 3D shape retrieval has become an important research topic in content-based 3D object retrieval. The aim of this track is to measure and compare the performance of non-rigid 3D shape retrieval methods implemented by different participants around

Specification for the Open Checklist Interactive Language (OCIL) Version 2.0

April 7, 2011
Author(s)
David A. Waltermire, Karen Scarfone, Maria Casipe
This report defines version 2.0 of the Open Checklist Interactive Language (OCIL). The intent of OCIL is to provide a standardized basis for expressing questionnaires and related information, such as answers to questions and final questionnaire results, so

Correlation of Variations in Thermoelectric and Microstructural Properties of P-type CeFe4Sb12 Melt-Spun Ribbons Using a Rapid Screening Method

April 6, 2011
Author(s)
Yonggao Y. Yan, Winnie K. Wong-Ng, James A. Kaduk, Gangjian Tan, Wenjie Xie, Martin L. Green, Xinfeng Tang
We have demonstrated the effect of gradients in both phase composition and microstructure of p-type CeFe4Sb12 melt-spun (MS) ribbons on Seebeck coefficient by a thermoelectric (TE) screening tool, in conjunction with XRD and DSC measurements. The spatial

From Electrons to Infrastructure: Engineering Concrete From The Bottom Up

April 6, 2011
Author(s)
Hamlin M. Jennings, Jeffrey W. Bullard
We argue that only an approach rooted in fundamental, mechanistic models of concrete materials offers a viable path for handling the enormous number of new variables that are being introduced as new materials are added to the design space, and as new

Magnetic Phase Diagram of Gd 2 Sn 2 O 7

April 6, 2011
Author(s)
R. S. Freitas, Jason S. Gardner
We have studied the magnetic phase diagram of the Heisenberg pyrochlore antiferromagnet Gd 2Sn 2O 7. Low temperature magnetic susceptibility measurements, as a function of the applied magnetic fields and temperature, shows the existence of multiple phase

Spin Liquid State in the S = 1/2 Triangular Lattice Ba 3 CuSb 2 O 9

April 6, 2011
Author(s)
H. D. Zhou, E. S. Choi, G. Li, L. Balicas, C. R. Wiebe, Yiming Qiu, John R. Copley, Jason S. Gardner
Spin liquids remain one of the most important objects of study in modern solid state physics as model systems of quantum magnetism. In this paper, we report the synthesis and characterization of a new spin liquid candidate, Ba 3CuSb 2O 9, which has a

Characterizing arbitrary CW waveforms with 1500 THz/s chirp rates

April 5, 2011
Author(s)
Ian R. Coddington, Fabrizio R. Giorgetta, Esther Baumann, William C. Swann, Nathan R. Newbury
A Dual frequency comb interferometer was constructed to monitor cw laser chirp rates exceeding 1500 THz/s with MHz level resolution and accuracy over a 3 THz spectral sweep. Monitoring of the chirped laser is continuous. Additionally, absolute frequency

Electrodeposition of Pt_(100-x)Pb_(x) Metastable Alloys and Intermetallics

April 4, 2011
Author(s)
Sun M. Hwang, John E. Bonevich, Jae Jeong Kim, Thomas P. Moffat
The electrodeposition of a series of metastable Pt-Pb alloys and intermetallic phases as well as elemental Pt is demonstrated using an acid electrolyte comprised of 0.05 mol/L Pb(ClO_4)_2 and/or 0.001 mol/L K_2PtCl_4. Pt-Pb films were deposited at various

Geographical variation of Persistent Organic Pollutants in eggs of threatened loggerhead sea turtles (Caretta caretta) from Southeastern USA

April 4, 2011
Author(s)
Jennifer M. Lynch, Juan Alava, Jeanette Wyneken, Larry Crowder, Geoffrey Scott, John R. Kucklick
Persistent organic pollutants (POPs) are a recognized man-made threat to sea turtle populations, but the uncertainty surrounding exposure and sensitivity of sea turtles to contaminants is great and makes decision making difficult for conservation managers

Research Directions in Security Metrics

April 4, 2011
Author(s)
Wayne Jansen
More than 100 years ago, Lord Kelvin observed that measurement is vital to deep knowledge and understanding in physical science. During the last few decades, researchers have made various attempts to develop measures and systems of measurement for computer

Superconformal Ni Electrodeposition using 2-Mercaptobenzimidazole

April 4, 2011
Author(s)
Chang H. Lee, John E. Bonevich, Ugo Bertocci, Kristen L. Steffens, Thomas P. Moffat
Ni superconformal filling of sub-micrometer trenches is demonstrated using a Watts bath containing an inhibitor 2-mercaptobenzimidazole (MBI). Hysteretic voltammetry marks the breakdown of the MBI-induced passive-state coincident with the onset of Ni
