Electrodeposition of diamond-like carbon films in organic solvents using a thin wire anode

Diamond-like carbon films (DLC) have been electrodeposited on silicon substrates in organic solvents using a thin tungsten wire anode under high potential. During the deposition, if the applied potential is sufficient enough, the spark could be observed even by the naked eye. It has been manifested that this method could produce an extreme environment which is favorable to form much more sp3 bonded carbon atoms compared with conventional electrolysis.
