Measurement and Modeling of Short and Medium Range Order in Amorphous Ta2O5 Thin Films

Amorphous films and coatings are rapidly growing in importance. Yet, there is a dearth of high-quality structural data on sub-micron films. Not understanding how these materials assemble at atomic scale limits fundamental insights needed to improve their performance. Here, we use grazing-incidence x-ray total scattering measurements to examine the atomic structure of the top 50-100 nm of Ta2O5 ...

Short-range order of compressed amorphous GeSe2

The structure of amorphous GeSe2 (a-GeSe2) has been studied by means of a combination of two-edges X-ray absorption spectroscopy (XAS) and angle-dispersive X-ray diffraction under pressures up to about 30 GPa. Multiple-edge XAS data-analysis of a-GeSe2 at ambient conditions allowed us to reconstruct and compare the first-neighbor distribution function with previous results obtained by neutron d...

Spatial variation of short-range order in amorphous intergranular complexions

SHORT RANGE ORDER IN ANNEALED FexSi1-x AMORPHOUS FILMS

Magnetic properties of as-prepared (sputtered) and annealed Fe,Sil-, (0.64 5 x 5 0.78) amorphous films deposited at room temperature, are interpreted in terms of chemical short-range order and compared with evaporated films deposited at 77 K. Low temperature ( 5 30 K) magnetization behaviour follows; M (T) / M (0) = 1 B T ~ / ~ c T ~ / ~ 2 with B = 1.5 x K ~ / ~ ; C = -2.610 x ~ K ~ / ~ . Relat...
