The interface of zirconium oxide thin films on silicon is analyzed in detail for their potential applications in the microelectronics. The formation of an interfacial layer of ZrSixOy with graded Zr concentration is observed by the x-ray photoelectro

Modeling x-ray absorption near edge structure (XANES) requires computationally intensive calculations. We show that parallel processing can reduce the time required for XANES calculations by a factor of up to 50 over standard desktop computers. Paral
Thermal expansion coefficients of low-k dielectric films from Fourier analysis of x-ray reflectivity

We determine the thermal expansion coefficient of a fluorinated poly(arylene ether) low-k dielectric film using Fourier analysis of x-ray reflectivity data. The approach is similar to that used in Fourier analysis of x-ray absorption fine structure.

When two or more absorption edges in a material are sufficiently close in energy, extended-x-ray-absorption-fine-structure spectroscopy is of limited utility as the usable data range above the lower-energy edge is truncated by the higher-energy edge.

Improved calculations of Bragg peak intensities near atomic resonance are obtained by including the effect of the local environment around the resonant atoms on the resonant scattering amplitudes $\ensuremath{\Delta}{f=f}^{\ensuremath{'}}{+if}^{\ensu

The local structure within the unit cell of strained-GeSi layers grown on Si(001) has been examined by polarization-dependent extended x-ray-absorption fine structure. First-neighbor bond lengths are found to deviate only slightly from their unstrain
