High Inversion Current in Silicon Nanowire Field Effect Transistors

November 30, 2004
Author(s)
Sang-Mo Koo, Jin-Ping Han, Eric M. Vogel, Curt A. Richter, J. Vahakangas, Akira Fujiwara
Silicon nanowire (SiNW) field effect transistors (FETs) with channel widths down to 20 nm have been fabricated by a conventional 'top-down?approach using electron-beam lithography. The SiNW device shows higher inversion channel current density than the

Observation of a geometrically constrained domain wall in epitaxial FCC Co small disks

May 1, 2004
Author(s)
C Vaz, L Lopez-Diaz, M Klaui, J Bland, T Monchesky, John Unguris, Z Cui
The magnetic nanostructure of epitaxial FCC Co/Cu(0 0 1) circular elements (1.7 m in diameter) has been imaged with scanning electron microscopy with polarization analysis. A closed flux configuration (quadrant configuration) is observed for most of the

Self-Assembled Monolayers Exposed by Metastable Argon and Metastable Helium for Neutral Atom Lithography and Atomic Beam Imaging

September 1, 1997
Author(s)
A Bard, K K. Berggren, J L. Wilbur, John D. Gillaspy, S L. Rolston, Jabez J. McClelland, William D. Phillips, M Prentiss, G M. Whitesides
We used a beam of noble gas atoms in a metastable excited state to expose a thin (1.5nm self-assembled monolayer resist applied over a gold-coated silicon wafer. We determined exposure damage as a function of dose of metastable atoms by processing the

Slow and static spin correlations in Dy 2+h Ti 2-hO d7-d

April 17, 2011
Author(s)
Jason S. Gardner, G. Ehlers, P. Fouquet, B. Farago, J. R. Stewart
The static and dynamic spin correlations in the spin-ices Dy 2.3Ti 1.7O 6.85 and Dy 2Ti 2O 7 have been studied in polarised neutron diffraction and neutron spin echo experiments. The measurements reveal that, below 100 mK, the magnetic scattering broadens

Absolute Flux Calibration of Stars; Calibration of the Reference Telescope

June 2, 2009
Author(s)
Allan W. Smith, John T. Woodward IV, Colleen A. Jenkins, Steven W. Brown, Keith R. Lykke
Absolute stellar photometry is based on 1970s terrestrial measurements of the star Vega with instruments calibrated using the Planckian radiance from a Cu fixed-point blackbody. Significant advances in absolute radiometry have been made in the last 30
