Propriétés optiques des superréseaux de a-Si : H /a-SiNx : H ont été étudiées en fonction d'épaisseur par la spectroscopie de la déflection photothermique et photoluminescence. Nous suggérons contamination, plutôt que des effets quantiques peut déterminer les propriétés optiques lorsque l'épaisseur est réduite au dessous de ∼ 30 Å.Optical properties of a-Si : H/a-SiNx : H superlattices have been investigated as a function of sublayer thickness by photothermal deflection spectroscopy and photoluminescence measurements. We suggest contamination, rather than quantum confinement effects, may determine optical properties when sublayer thickness is reduced below ∼ 30 Å
