Structural ordering of diamond like carbon films by applied electric field

Abstract

Diamond like carbon films deposited by RF magnetron sputter deposition technique contain both SP 2 and SP 3 hybridized carbons. These films are structurally disordered and inhomogeneous. By the application of electric field across the film, these films are transformed to a more orderly structured diamond like carbon, bringing homogenity in the film. This transformation has resulted in the increase of the reflectivity of the metal(Aluminum), which is used as one of the electrodes for applying the electric field, by 5 times.
