摘要:
A carbon cluster film has a precisely controlled stable electrical conductivity which does not deteriorate in a short period of time in air. Such a carbon cluster film having a stable electrical conductivity is formed by introducing an impurity into a thin film of fullerenes by ion implantation. The fullerenes include C.sub.60, C.sub.70 or the like.
