The integration of silver thin films into optoelectronic devices has gained much interest due to their exceptional properties in terms conductivity and compatibility with flexible substrates. For this type application, ultra-thin layers are desirable, because optical transparency. Standard direct current magnetron sputtering (DCMS) is known lead undesirable formation islands at low effective film thicknesses on typical substrates like SiO2 or polystyrene (PS). Therefore, study, we explore...
Plasmons have facilitated diverse analytical applications due to the boosting signal detectability by hot spots. In practical applications, it is crucial fabricate straightforward, large-scale, and reproducible plasmonic substrates. Dewetting treatment, via applying direct thermal annealing of metal films, has been used as a straightforward method in fabrication such nanostructures. However, tailoring evolution dewetting process films poses considerable experimental complexities, mainly...
The pristine micellar pattern of the diblock copolymer PS- b -P4VP degrades upon drying a water droplet, which can be stabilized and inhibited deposition silver clusters.
Energy flux measurements by a passive thermal probe were performed for diffuse coplanar surface barrier discharge to determine the transfered energy substrate in dependence on distance electrode and working gas of discharge. The largest was found at ∼300–400 m above be about 900 mW cm−2. Furthermore, an active cooling mechanism could identified within plasma caused convection flows very small distances. Variation (argon, molecular gas) indicates importance reactivity transferred substrate....
In situ GIWAXS and GISAXS investigations reveal that pre-deposited Au nanoparticles can act as nuclei or growth cores adsorb sputtered Ag atoms, resulting in the fast formation of an ultra-thin layer.
Electrical and calorimetrical measurements were performed to obtain insight into the energy transformation from input power available for plasma treatment of substrates in a diffuse coplanar surface barrier discharge used as source operated air, N2, O2, CO2 at up 380 W. Overall applied electrical measured, conversion 90% was determined with constant loss 30 W operation control unit. Measurements temperature gradient electrode oil cooling identify due cooling. With roughly 50% power, it...
Fabricating thin metal layers and particularly observing their formation process in situ is of fundamental interest to tailor the quality such a layer on polymers for organic electronics. In particular, high power impulse magnetron sputtering (HiPIMS) establishing has sparsely been explored situ. Hence, this study, we investigate growth gold (Au) with HiPIMS compare Au prepared by conventional direct current (dcMS). was chosen because it an inert noble scattering length density. This allows...
Abstract Passive thermal probes were applied on two different plasma spraying devices to gain a detailed understanding of the energy flux towards substrate under atmospheric pressure. The challenge very high load was solved by using an advanced time-resolved measuring and evaluation technique. combination with controlled movement jets allowed obtain insightful radial profiles. changes linearly electrical input power. When adding diatomic gases (H 2 / N ) gas mixture increases significantly,...
