Nickel silicides include several intermetallic compounds of nickel and silicon. Nickel silicides are important in microelectronics as they form at junctions of nickel and silicon. Additionally thin layers of nickel silicides may have appliion in imparting surface resistance to nickel alloys.
Laser fabriion of silicon carbide detector for gas …
The detector absorbs the photons and the absorbed photon energy modifies the electron density in the semiconductor by the photoexcitation, leading to changes in the refraction index. Ga is known to have an energy level of 0.30 eV in n-type 4H-SiC substrates, which corresponds to the wavelength 4.21 μm.
Brewster Windows | II-VI Incorporated
Rectangular Brewster windows are uncoated substrates used in an optical system at Brewster’s Angle, the angle at which p reflectance drops to zero. This can be calculated from: ΘB = tan-1(n) where ΘB is Brewster’s Angle and n is the material’s index of refraction.

In this work, optical coatings with a gradient of the refractive index are described. Its aim was to deposit, using the RF PECVD method, films of variable composition (ranging from silicon carbon-oxide to silicon carbon-nitride) for a smooth change of their optical properties enabling a production of the filter with a refractive index gradient. For that purpose, two organosilicon compounds

Measurement of thickness profile and refractive index …
We developed a method to measure the thickness profile and refractive index variation for silicon wafers based on a spectral-domain interferometry. Through a spectral domain analysis of multiple interferograms obtained using a femtosecond pulse laser, two physical quantities, the thickness profile and the refractive index variation can be measured at high speed.

Index of Refraction – IR materials vary in terms of index of refraction far more than visible materials do, allowing for more variation in system design. Unlike visible materials (such as N-BK7) that work well throughout the entire visible spectrum, IR materials are often limited to a small band within the IR spectrum, especially when anti-reflection coatings are applied.
