Annealing of gold nanostructures sputtered on polytetrafluoroethylene
Gold nanolayers sputtered on polytetrafluoroethylene (PTFE) surface and their changes induced by post-deposition annealing at 100°C to 300°C are studied. Changes in surface morphology and roughness are examined by atomic force microscopy, electrical sheet resistance by two point technique, zeta potential by electrokinetic analysis and chemical composition by X-ray photoelectron spectroscopy (XP...
متن کاملProperties of gold nanostructures sputtered on glass
We studied the electrical and optical properties, density, and crystalline structure of Au nanostructures prepared by direct current sputtering on glass. We measured temperature dependence of sheet resistance and current-voltage characteristics and also performed scanning electron microscopy [SEM] analysis of gold nanolayers. It was shown that within the wide range of temperatures, gold nanolay...
متن کاملEffects of substrate annealing on the gold-catalyzed growth of ZnO nanostructures
The effects of thermal substrate pretreatment on the growth of Au-catalyzed ZnO nanostructures by pulsed laser deposition are investigated. C-plane sapphire substrates are annealed prior to deposition of a thin Au layer. Subsequent ZnO growths on substrates annealed above 1,200°C resulted in a high density of nanosheets and nanowires, whereas lower temperatures led to low nanostructure densitie...
متن کاملAnnealing effect on ion-beam-sputtered titanium dioxide film.
We found that the extinction coefficient of ion-beam-sputtered titanium dioxide films first decreased with increasing annealing temperature then increased drastically when annealing temperature was increased above ~200 degrees C for 24 h of annealing time. The decreasing extinction coefficient with annealing temperature was attributed to a reduction in absorption owing to oxidation of the film ...
متن کاملEvolution of gold nanostructures on graphene.
or exposure to a hydrogen plasma. [ 5 ] Metal–graphene interactions have been much studied theoretically, in terms of the specifi c sites of the metals on the benzene ring, their binding energies etc. So, for example, center-ring positions (H sites) are predicted as preferred locations for most metals (e.g., Ti, Fe), corner sites directly above C atoms (T sites) for Sb, Sn, and Ni, and bridge s...
