Abstract

The electron transport path that depends strongly on the nondiamond carbon content in undoped polycrystalline diamond films was studied by examining the spatial distribution of emission sites and the electrolytic decoration method. Results indicate that electron transport preferentially through the conductive grain boundaries for the case of film with a large amount of nondiamond carbon, while electron transport occurs mainly through the diamond surface for film with a relatively small amount of nondiamond carbon.
