Abstract
Under normal process conditions UltraNanoCrystalline Diamond (UNCD) films are highly electrically insulating, but they can become highly conducting when Ar is substituted in the synthesis gas with some of N2. The potential utility of these films that provide the only currently available source of n-type diamond material conducting at ambient temperatures makes interesting to gain a better understanding of the mechanism underlying the insulator-metal transition [1].
