WebJun 27, 2014 · Results of spectroscopic ellipsometry (SE) reveal that the refractive indices ( n) of the ALD films are systematically lower than that of crystalline α-Al 2 O 3 in the wavelength range, 240–850 nm. Higher deposition temperature increased slightly the n values, but at the same time it also increased the roughness of the film surface. WebThe refractive index is a function of the wavelength.The most common characteristic quantity for characterization of an optical glass is the refractive index n in the middle range of the visible spectrum. This principal refractive index is usually denoted as n d – the refractive index at the wavelength 587.56 nm or in many cases as n e at the ...
