Abstract

Commercially prepared (100) oriented silicon wafers were oxidized to produce SiO₂ layers of 5 μm, 970 nm, 650 nm and 103 nm. Each sample was annealed at 1050°C for 1 h in a forming gas ambient. The photoluminescence (PL) emission was collected with f4 optics consisting of two matched plano-convex lens of 50 mm diameter and 200 mm focal length, giving a collection angle of up to ±7°. The distortions were shown to be simple consequence of the wavelength dependent reflectivity of the sample structure.
