Abstract

We have reported that the single impact of highly charged Ar ion (Ar/sup 8+/) on HOPG (highly oriented pyrolytic graphite) surface and the following electron injection onto the impact region transfer sp/sup 2/ to sp/sup 3/ hybridization in nanoscale, providing the drastic change of conductivity of the impact region. In the present study, we have discussed the defective structure created by Ar/sup 8+/ impact and the control of material property by combination with the post treatment.
