Persistent Oscillations of X-ray Speckles: Pt (001) Step Flow
M. S. Pierce, D. Hennessy, K. C. Chang +5
We have performed coherent x-ray scattering experiments on the hexagonally reconstructed Pt (001) surface to study the temperature-dependent surface dynamics. By correlating speckl…
Surface X-ray Speckles: Coherent Surface Diffraction from Au (0 0 1)
M. S. Pierce, K. C. Chang, D. Hennessy +4
We present coherent speckled x-ray diffraction patterns obtained from a monolayer of surface atoms. We measured both the specular anti-Bragg reflection and the off-specular hexagon…
Resonance Anomalous Surface X-ray Scattering
Andreas Menzel, Kee-Chul Chang, Vladimir Komanicky +4
Resonance anomalous surface x-ray scattering (RASXS) technique was applied to electrochemical interface studies. It was used to determine the chemical states of electrochemically f…
Polarization-Dependent Resonant Anomalous Surface X-ray Scattering of CO/Pt(111)
Andreas Menzel, Yuriy V. Tolmachev, Kee-Chul Chang +4
Polarization dependence of resonant anomalous surface x-ray scattering (RASXS) was studied for interfaces buried in electrolytes or in high-pressure gas. We demonstrate that RASXS…
Arrays of widely spaced atomic steps on Si(111) mesas due to sublimation
Kee-Chul Chang, Jack M. Blakely
Steps with spacings of microns form on top of mesas fabricated on Si(111) that is annealed at temperatures where sublimation becomes important. Upon annealing, mesas first develop…
