Thank you, But sorry for late reply,

How to maintain stiochiometry during synthesis of any thin film.

For metal oxides thin films,

100% stochiometric is not possible I think, if it is it may act as an insulator.We can control non-stoichiometry by adjusting the experimental conditions. If oxygen is not sufficient it forms non-stoichiometric -metaloxide films. The metal ions are not balanced in valence -oxygen deficiency gives rise to (excess metal).
