A Platform for Practical Nanophotonic Systems Nitrides and Oxides for Integrated Plasmonic Devices
… has largely been limited to the use of noble metals as plasmonic materials, largely due to the high conductivity (low loss) and wide availability in research institutions. However, the research which follows focuses on the development of two alternative material platforms for nanophotonics: …

Intermetallic compounds by reductive annealing
… a new synthetic route to binary and ternary intermetallic compounds, which avoids the need for reaction at very high temperatures, multi-step reactions, reaction under vacuum and/or the synthesis of precursors. The route was adapted from a synthetic route reported for the synthesis of ternary and …

Materials For Energy: Complex Oxides And Nitrides For New Polymer Electrolyte Membrane Fuel Cell Catalysts And Supports
… DiSalvo group has focused on doped, conducting metal oxides, yet materials with suitable conductivities have been difficult to prepare. In this work, binary and ternary transition metal nitrides are explored as potential replacements for carbon-based catalyst supports. Many nitrides have the …

"Reactive hard templating" : from carbon nitrides to metal nitrides
… scale by classical templating approaches. Metal nitrides are such kind of materials. They are usually produced by the conversion of metals or metal oxides in ammonia flow at high temperature (T > 1000°C), which make the application of classical templating techniques difficult. Graphitic …

Zirconium nitride contacts for cadmium telluride solar cells
… μΩ-cm, comparable to that of good conductive metals, which would permit thin back contacts. Annealing at temperature up to 270°C for 30 minutes did not affect the structure or properties of the ZrN. The effect of the thickness of the ZrN films on their back contact performance was studied. As …
