CrBx thin films with 1.90 ? x 2.08 have been deposited by direct-current magnetron sputtering (DCMS) from a stoichiometric CrB2 target at 5 and 20 mTorr (0.67 2.67 Pa) Ar pressure onto sapphire (0001) substrates. All films, irrespective of deposition conditions, exhibit texture. Attesting to the achievement close-to-stoichiometric composition, epitaxial film growth is observed 900°C, while 500 ...

Chromium oxide (α-Cr2O3) thin films were prepared using thermal annealing of chromium (Cr)films deposited on quartz substrates by direct current (DC) magnetron sputtering. The annealingprocess of the films was performed for different times of 60, 120,180 and 240 min. The influenceof annealing time on structural, morphological and optical properties of the prepared films wasinvestigated by diffe...

The aim of this paper is to study the effect of substrate on the Cu3N thin films. At first Cu3N thin films are prepared using DC magnetron sputtering system. Then structural properties, surface roughness, and electrical resistance are studied using X-ray diffraction (XRD), the atomic force microscope (AFM) and four-point probe techniques respectively. Finally, the results are investigated and c...

using c2h2, 112 and as gases at 550'c, carbon nanotubes were fabricated on the surfaces of twosubstrates coated by nano thin layers of metal catalysts by dc magnetron sputtering. aystamless steel andfe/cteal, by thermal chemical vapor deposition (tcvd) the surface properties of the substrates wereparticularly investigated, and the effect of treatment of the substrates on the cnt's growth is cri...

nanostructures of noble metal materials have been used in organic solar cells for enhancement of performance and light trapping. in this study, we have introduced branched silver cauliflower-like nanopatterns as sub-wavelength structured metal grating in organic solar cells. self-assembled fabrication process of branched nanopatterns was carried out on a bio-template of cicada wing nanonipple a...
