I am trying to functionalize my thin film surface with plasma. I am hopeful that mixture of hydrogen and oxygen plasma might work. I have read somewhere about it but couldn't find exact conditions for that.
Yes, it could be. Do google, if you don't find, in that case you should optimize tha parameters to produce plasma. This would be a valuable and novel contribution in this area. You have a golden opportunity. Garb it and do hard work. Go for Hit and trail. All the best
