f-forigin of the insulating state in uranium dioxide: X-ray absorption experiments and first-principles calculations

Autor: Jonathan C. Crowhurst, W. Siekhaus, S-W Yu, Sangeeta Sharma, Wanli Yang, James G. Tobin, J. K. Dewhurst, Paul Olalde-Velasco

Publikováno v: Physical Review B. 83

We have performed x-ray absorption experiments on uranium dioxide (UO${}_{2}$) at the O $1s$, U $4d$, U $4f$, and U $5d$ edges. After comprehensive energy calibrations for O $1s$, U $4d$, and U $4f$ spectra, we have used the U $4d$ and $4f$ spectra t

Scanning tunneling microscopy study of the structure of sulfur [2(3)1/2×2(3)1/2] R 30° overlayer on rhenium (0001)

Autor: Bruno Marchon, Thomas P. Beebe, Gabor A. Somorjai, Carmen Ocal, Miquel Salmeron, D.F. Ogletree, W. Siekhaus

Publikováno v: Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films. 8:297-301

The structure of the (2(3)1/2×2(3)1/2) R30° sulfur overlayer chemisorbed on rhenium(0001) has been studied with scanning tunneling microscopy (STM). The ordered sulfur overlayer was prepared in ultrahigh vacuum and then transferred through air to a

Defect studies of optical materials using near-field scanning optical microscopy and spectroscopy

Autor: M Yan, T Huser, J McWhirter, W Siekhaus

Defects and impurities are generally the key material properties that govern the quality and useful lifetime of optical components. Progress in materials synthesis has advanced so that today, for high power laser applications such as the National Ign

Characterization of surface and sub-surface defects in optical materials using the near field evanescent wave

Autor: M. Yan, S Oberhelman, L Wang, W Siekhaus, M Kozlowski

Optical properties of sub-micron defects at and near the surface are of interest in many applications, e.g. in high power laser systems where initiation of laser induced damage is a critical issue. In-situ scanning atomic force microscopy (AFM) has b

Atmospheric tarnishing of silver-plated laser mirrors

Autor: C. Marshall, H. Gregg, N. Thomas, A. Erlandson, W. Siekhaus, L. Chase, J. Farmer, S. Payne, Eric C. Honea, T. Parham

Purified air is being considered as a cost-effective alternative to evaporated liquid nitrogen for cooling laser amplifiers in the National Ignition Facility (NIF). Atmospheric corrosion of the associated flashlamp reflectors could cause significant
