For this purpose, spectroscopic ellipsometry is particularly suitable because hereby the influence of substrate properties can be neglected and no

Therefore, we conclude that CHx bonds are integrated within the volume of the PE-ALD layers at lower temperatures, whereas carbon contamination and carbonate formation is occurring at the surface. Conclusion Thin homogenous Al2O3 layers were
