Abstract

The impedance spectroscopy measurements were used to investigate the separated contributions of diamond grains and grain boundaries (GBs), giving an insight into p-type to n-type conductivity conversion in O⁺-implanted ultrananocrystalline diamond (UNCD) films. It is found that both diamond grains and GBs promote the conductivity in O⁺-implanted UNCD films, in which GBs make at least half contribution. The p-type conductivity in O⁺-implanted samples is a result of H-terminated diamond grains, while n-type conductive samples are closely correlated with O-terminated O⁺-implanted diamond grains and GBs in the films. The results also suggest that low resistance of GBs is preferable to obtain high mobility n-type conductive UNCD films.
