Abstract The volumetric thermal expansion coefficient α V is discussed in relation to the bulk modulus B 0 for transition-metal disilicides (TrSi 2 ), alkaline-Earth metal (AeSi Mg Si, and Si clathrates. For this purpose, of CoSi at 300 K determined be 3.1 × 10 −5 −1 using powder X-ray diffraction measurements temperatures ranging from 835 K. AeSi have values 27.9 52.9 GPa, while range 3.2 4.8 ...

This paper presents a study of Ni-silicides as the bottom electrode of HfO2-based RRAM. Various silicidation conditions were used to obtain different Ni concentrations within the Ni-silicide bottom electrode, namely Ni2Si, NiSi, and NiSi2. A 10nm HfO2 switching material and 50nm TiN top electrode was then deposited and etched into 500nm by 500nm square RRAM cells. Cell performance of the Ni2Si ...

Self-aligned nanostructures (SAN) made by reacting Co nanoparticles with crystalline Si substrates at high temperatures were studied with grazing incidence X-ray absorption spectroscopy (GI-XAS). The results from extended X-ray absorption fine structure (EXAFS) analysis and X-ray absorption near-edge spectroscopy (XANES) were used to identify SAN as crystalline CoSi2. Theoretical calculations o...

Nickel silicides (NiSi) are renowned for their ability to withstand high temperatures and resist oxidation corrosion in challenging environments. As a result, these alloys have garnered interest potential applications turbine blades underwater settings. However, brittleness is constant obstacle that hinders use producing larger parts. A literature review has revealed incorporating trace amounts...
