Refractive Index of AlN, Aluminium Nitride. Aluminium nitride (AlN) is a nitride of aluminium. Its wurtzite phase (w-AlN) is a wide band gap (6.2 eV) semiconductor material, giving it potential application for deep ultraviolet optoelectronics. For a typical sample of AlN the refractive index and extinction coefficient at 632.8 nm are 2.16468 and 0.
Refractive Index Database The table below contains links to refractive index data for common materials. Each material in the database has refractive index listed as a function of wavelength over a range typically required for thin-film thickness measurement. Refractive Index of Al2O3 Aluminium oxide is the family of inorganic compounds with the chemical formula Al2O3. It is an amphoteric oxide and is commonly referred to as alumina, corundum as well as many other names, reflecting its widespread occurrence in nature and industry. The resultant film had a resistivity of 4.7x10 -4 ω·cm. A variable-angle ellipsometer was used to take amplitude and phase change measurements. The refractive index and extinction coefficient was extracted from a multi-oscillator model fit to the ellipsometry data, as a function of wavelength, from 300 to 900 nm.
