We review the design and fabrication of thin-film composite optical waveguides (OWG) with high refractive index for sensor applications. A highly sensitive optical sensor device has been developed on the basis of thin-film, composite OWG. The thin-film OWG was deposited onto the surface of a potassium-ion-exchanged (K(+)) glass OWG by sputtering or spin coating (5-9mm wide, and with tapers at b...

Yttria-stabilized zirconia (YSZ) thin films were deposited using direct current (reactive and metallic) radio frequency magnetron sputtering. The effect of the deposition technique annealing treatment on microstructure crystallinity was assessed. Using produced in this work, oxygen gas sensors built their performance under vacuum conditions evaluated. All exhibited a cubic crystalline structure...

When titanium dioxide (TiO2) is exposed to nearultraviolet light, it exhibits strong bactericidal activity. Anatase phase of TiO2 film was prepared by anodizing pure titanium coupons (substrate). Atomic force microscopy (AFM) technique was used to image the transformation of titanium surface to TiO2 surface on anodization. We observed wide distribution of TiO2 particles ranging from submicron t...

Titanium nitride is an attractive material for a range of superconducting quantum-circuit applications owing to its low microwave losses, high surface inductance, and chemical stability. The physical properties device performance, nevertheless, depend strongly on the quality materials. Here we focus highly crystalline epitaxial titanium thin films deposited sapphire substrates using magnetron s...

Abstract DC magnetron sputtering was used to deposit titanium (Ti), nitride (TiN), and Ti/TiN multilayer coatings on Ti6Al4V alloy substrates. The have 1, 4, 10, 16, 32 modulation periods respectively. SEM were analyze the surface cross-sectional micro-features of coatings. Electrochemical tests carried out 3.5 wt% NaCl solution at room temperature. resistance coating reaches maximum value, whi...

Superconducting thin films have the potential to overcome fundamental limitations of bulk niobium technology that is currently implemented in linear particle accelerators. Before these thin films can successfully be implemented, systematic studies on structureproperty correlations are necessary. Here, we present the characterization of niobium nitride thin films and multilayers. We explore the ...

The paper demonstrates study results of the processes reactive magnetron sputtering a Ti-Al composite target in an Ar/O 2 gas mixture with various methods supply to chamber. It has been established that, regardless method supply, when changing oxygen concentration mixture, ratio Al and Ti content deposited 1-x x O y films changes. metal varies proportion change control lines intensities optical...

The structure and nanoscale mechanical properties of Ni48.8Mn27.2Ga24 thin film fabricated by DC magnetron sputtering are investigated systematically. The thin film has the austenite state at room temperature with the L21 Hesuler structure. During nanoindentation, stress-induced martensitic transformation occurs on the nanoscale for the film annealed at 823 K for 1 hour and the shape recovery r...
