“…The changes in the structural parameters affected the surface characteristics and functional properties of the deposited coatings. As previously demonstrated and analyzed in [6], the X-ray diffraction profiles of as-deposited Ta2O5 coatings prove the amorphous nature for as-deposited magnetron sputtered Ta2O5 coatingsno peaks are observed. The Ta 4f lines of the deposited films are in a good agreement with the Ta 4f doublet representative of the Ta-O bond in Ta2O5.…”

The effect was analyzed of surface treatment by argon ions and electron beam on the properties of tantalum pentoxide coatings deposited by reactive magnetron sputtering and the treatment’s correlation with immune cells response. The characteristics of the coatings were determined by means of energy dispersive X-ray (EDX) scanning electron microscopy (SEM), X-ray photoemission spectroscopy (XPS), and atomic force microscopy (AFM). The results demonstrate that the electron-irradiation post-treatment process stimulates the adhesive potential and phagocytic activity of antigen-presenting cells.

“…The volt-ampere characteristics of the magnetron discharge with tantalum target in argon for different values of the reactive gas flow were presented previously [6]. The deposition process carried out with simultaneous bombardment by argon ions resulted in structural changes of the growing films.…”

“…Films are characterized with Nanomap 1000, a non-contact optical profilometer for measuring RMS surface roughness R q , and average surface roughness R a . An optical profilometer evaluates the surface roughness with phase shift interferometry utilizing the reflected light from the sample [30][31]. Surface roughness images of a bare substrate of Fused silica are shown in Figure 10 and corresponding values are tabulated in Table VI.…”

Investigation of deposition conditions on structural, optical, and surface properties of Tantalum pentaoxide (Ta2O5) thin films deposited without assisted ion beam (Single Ion Beam Sputtering technique, SIBS) and with assisted ion beam (Dual Ion Beam Sputtering technique, DIBS) is carried out. For both SIBS and DIBS identical coating process conditions are applied for deposition of Ta2O5 films onto highly polished and clean, fused silica substrates. Estimation of deposition rates of Ta2O5 with identical beam energies and coating chamber conditions is done. Benefits of O2 assist beam on the behavior of structural, optical, and surface properties of thin films deposited are studied. The films are characterized with an ellipsometer, optical profilometer, XRD, FE-SEM, and XPS techniques to bring the merits films coated of Ion Beam Sputtering deposition with and without assist Ion Beam. Configuration of ion sources and targets in the coating chamber for DIBS of oxide targets is carried out in the present work are useful for multi-layer coatings for high reflectivity mirrors for electro-optical instruments like ring laser-based rotation sensors.
