Damage on surface and in bulk of highly oriented pyrolytic graphite (HOPG) induced by variety of heavy ions was studied by scanning tunneling microscopy (STM). Hillocks rather than hollows were observed either on the original sample surfaces or on the cleaved surfaces. Compared to the original surface
the probability of track formation was significantly reduced in the deeper bulk layers. This could be understood by assuming a morphology consisting of a discontinuous sequence of damage segments instead of a homogeneous cylinder.
