1. Fabricating HD-2(Fe) type Gas Proportional Counters: A Practical Guide to Techniques, Procedures and Operations
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7936
Topic: Environment/Climate
Published: 6/5/2013
Authors: George A Klouda, Jeffrey R. Anderson, John E Fuller III
Abstract: Over the last eight years, gas (filled) proportional counters (GPCs) of the HD-2(Fe) type (Davis et al., 1968, 1972; Wink et al., 1993) have been fabricated at NIST through a collaboration of the Materials Measurement Science Division, Facility f ...

2. All-angle negative refraction and active flat lensing of ultraviolet light
Topic: Environment/Climate
Published: 5/22/2013
Authors: Ting Xu, Amit Kumar Agrawal, Maxim Abashin, Kenneth John Chau, Henri J Lezec
Abstract: The ability of a left-handed medium to sustain backwards electromagnetic waves leads to counter-intuitive phenomena such as negative refraction. We report the experimental implementation of a three-dimensional negative-index metamaterial operating at ...

3. Enhancing 9 nm Node Dense Patterned Defect Optical Inspection using Polarization, Angle, and Focus
Topic: Environment/Climate
Published: 4/10/2013
Authors: Bryan M Barnes, Francois Romain Francis Goasmat, Martin Yeungjoon Sohn, Hui Zhou, Abraham Arceo
Abstract: To measure the new SEMATECH 9 nm node Intentional Defect Array (IDA) and subsequent small, complex defects, a methodology has been used to exploit the rich information content generated when simulating or acquiring several images of sub-wavelength-si ...

4. 3-D Optical Metrology of Finite sub-20 nm Dense Arrays using Fourier Domain Normalization
Topic: Environment/Climate
Published: 3/25/2013
Authors: Jing Qin, Hui Zhou, Bryan M Barnes, Ronald G Dixson, Richard M Silver
Abstract: Reduced target dimensions requiring improved resolution and sensitivity have driven the need to use and analyze the phase and scattered frequency information available when using image-based scatterometry systems. One such system is scatterfield micr ...

5. SCATTERFIELD MICROSCOPY, REVIEW OF TECHNIQUES THAT PUSH THE FUNDAMENTAL LIMITS OF OPTICAL DEFECT METROLOGY
Topic: Environment/Climate
Published: 3/25/2013
Authors: Richard M Silver, Bryan M Barnes, Francois Romain Francis Goasmat, Hui Zhou, Martin Yeungjoon Sohn
Abstract: The semiconductor manufacturing industry is now facing serious challenges in achieving defect detection rates with acceptable throughput and accuracy. With conventional bright-field and dark- field inspection methods now at their limits, it has b ...

6. Discriminating the states of matter in metallic nanoparticle transformations: What are we missing?
Topic: Environment/Climate
Published: 2/20/2013
Authors: John M. Pettibone, Julien Claude Maurice Gigault, Vincent A Hackley
Abstract: A limiting factor in assessing the risk of current and emerging nanomaterials in biological and environmental systems is the ability to accurately detect and characterize their size, shape and composition in broad distributions and complex media. Asy ...

7. Protective performance of environmentally stressed fabrics containing melamine fiber blends
Topic: Environment/Climate
Published: 1/12/2013
Authors: Shonali Nazare, Shaun M. Flynn, Rick D Davis, Joannie W Chin
Abstract: In this study, environmentally stressed OS fabrics containing melamine fiber blends were evaluated for thermal and mechanical properties that are critical to the protective performance of firefighter turnout gear. Environmental stress factors that a ...

8. Spectroscopy and imaging of edge modes in Permalloy nanodisks
Topic: Environment/Climate
Published: 1/3/2013
Authors: Feng Guo, Lyubov Belova, Robert D McMichael
Abstract: This paper reports spectroscopy and imaging of spin wave modes using ferromagnetic resonance force microscopy (FMRFM) in Permalloy nano-disks with disk diameters that range from 100 nm to 750 nm. The ferromagnetic resonance spectra distinguish multip ...
