We investigated the variation of atomic oxygen density for various mixtures of O2/insulating gas and report a significant five-fold increase of [O] when oxygen plasma was diluted with sf6 gas by only 5%. We attribute this increase in [O] to a combination of a change in surface conditions caused by constituents of gaz sf6 plasma reacting with the reactor walls andGet price
