摘要: Abstract The optical properties of thin sputter-deposited A1N films on Si were measured. It is shown that they depend the exact preparation conditions. In visible range, refractive index n fitted by = c1 exp(-λ/c2) + c3, where 2.09 and c2 131.9 nm are constant c3 ≈ 1.8 –2.5 depending also chromaticity coordinates vary quasi-periodically with product its thickness.
