I am currently studying the properties of Al2O3 films through Atomic Layer Deposition, and I use Aluminum contacts for my MIM Structures. However I noticed that when I put a piece of Si Wafer and a piece of corning glass with a 100 nm Aluminium thick film in the reacton chamber, I can get growth of Al2O3 on the Si Wafer, but not on the Aluminum film. Has anyone ever encountered this problem? At the moment I only found this article that talks about the subject, but they had no problems with the deposition: https://arxiv.org/pdf/1309.4404.pdf

Thank you.
