Comparative Study of Al2O3 Optical Crystalline Thin Films Grown by Vapor Combinations of Al(CH3)3/N2O and Al(CH3)3/H2O2

Abstract
We compared the use of nitrous oxide (N2O) and hydrogen peroxide (H2O2) as the oxidant in digital chemical vapor deposition to obtain high-quality optical crystalline thin films of Al2O3. Optical constants and thicknesses of these films were investigated in terms of growth temperature, by using variable-angle spectroscopic ellipsometry.
