Microstructure Evaluation of Nano-thick Au-inserted Nickel Silicides

Controlled assembly of graphene-capped nickel, cobalt and iron silicides

The unique properties of graphene have raised high expectations regarding its application in carbon-based nanoscale devices that could complement or replace traditional silicon technology. This gave rise to the vast amount of researches on how to fabricate high-quality graphene and graphene nanocomposites that is currently going on. Here we show that graphene can be successfully integrated with...

Diffusion and redistribution of boron in nickel silicides

The diffusion and solubility of B implanted in δ-Ni2Si and NiSi layers is studied by SIMS. It is observed that both diffusion and solubility are higher in δ-Ni2Si than NiSi. The redistribution of B during Ni silicidation is also studied. The SIMS profiles show the presence of concentration step in the middle of the final NiSi layer. This profile shape is explained in light of the results obtain...

Characterization and Modeling of Stress Evolution during Nickel Silicides Formation

An curvature measurement technique was used to characterize the stress evolution during reaction of a Ni film and a silicon substrate to form nickel silicide. Stress changes were measured at each stage of the silicide growth. When the nickel films were subjected to longtime isothermal annealing, stresses that developed during silicide formation gradually relaxed. Fitting the experimental result...

Process Development & Microstructure & Mechanical Property Evaluation of a Dual Microstructure Heat Treated Advanced Nickel Disc Alloy

This paper summarises Rolls-Royce’s efforts in developing a production capable and industrially robust process for the production of dual-microstructure components. This has been possible through the use of process modeling, full-scale validation trials, detailed microstructural assessment through a variety of destructive and non-destructive methods and mechanical property evaluation. This pape...
