Effect of Polyethylene on Low Pressure Diamond Growth from the Vapour Phase

Effect of polyethylene on low pressure diamond growth from the vapour phase was studied. It was found that diamond nucleation on polyethylene coated, un-polished single crystal silicon substrate was greatly enhanced. The mechanism of the observed enhancement and a new concept of the super-saturation of carbonaceous radicales with the SP3 hybridstructure which enhance the nucleation of diamond film have been proposed.
