In this study, titanium nitride (TiN) is synthesized using reactive sputtering for a self-aligned gate process. The Schottky barrier height of the TiN on n-GaN is around 0.5 to 0.6 eV and remains virtually constant with varying nitrogen ratios. As compared with the conventional Ni electrode, the TiN electrode presents a lower turn-on voltage, while its reverse leakage current is comparable with...

Application of surface modification methods is expected to be a supreme solution to diminishing fretting damage. In this study, our aim was to improve the fretting fatigue life of Al7075-T6 alloy by covering it with a TiN thin film hard coating using the magnetron sputtering technique. Coated specimens with the best surface hardness, adhesion strength and roughness were tested with a rotating b...

We report measurements of ion energy distributions of ionized species in titanium and aluminium filtered cathodic vacuum arcs operating in oxygen and nitrogen gas atmospheres. The ion energy distributions were recorded using a Hiden mass selected ion energy analyzer. The results show that a significant reduction in ion energies and a change in the shape of ion energy distributions occurs as the...

P A P ER Abstract The broadband enhancement of single–photon emission from nitrogen-vacancy centers in nanodiamonds coupled to a planar multilayer metamaterial with hyperbolic dispersion is studied experimentally. The metamaterial is fabricated as an epitaxial metal/dielectric superlattice consisting of CMOS-compatible ceramics: titanium nitride (TiN) and aluminum scandium nitride (AlxSc1-xN). ...

The Polish ventricular assist device, POLVAD_EXT, is made of a polymer designed to be covered with a nanocoating of titanium nitride to improve haemocompatibility. A loss of cohesion can occur between the coating and the substrate. An analysis of stress and strain states in a multi-scale model of the blood chamber was performed in the finite element computer program, VADFEM. The multiscale mode...

This retrospective study examined the medium term outcome of 305 Titanium Nitride (TiN) Mobile bearing total knee. At ten years after the start of the study, there was a significant improvement (p < 0.0001) in the post-operative knee scores. The ten year survival with revision for any reason as the end point was 95.1% (95% CI 92.4 to 97.8). The ten year survival rate with revision for aseptic l...

The purpose of this investigation was to develop a coating technique and to study the characteristics of titanium–aluminum nitride [(Ti,Al)N] films deposited on a base-metal alloy (Wiron88R) substrate. Titanium–aluminum nitride thin films were deposited on the alloy surface using a reactive radiofrequency sputtering method. The electrochemical properties of three specimens with and without coat...

This is the final technical report for the KISS Technical Development program entitled “Development of Ultrasensitive Photon Detectors and Microwave Amplifiers Using Superconducting Nitride Thin Films”. The Technical Development phase started in January 2011 and concluded in December 2012. The overall goal of this program was to explore the application of high-resistivity superconductors, parti...

A thin film coating of titanium nitride was applied to the surface of rf cavity tuners to reduce secondary electron generated when the existing copper base material is in place. The tuners are used in high-field gradients, where electron heating of the tuner is a problem. By reducing the generation of electrons the temperature of the tuners will be reduced, for better reliability. This paper co...
