Abstract

The authors discuss changes in the elastic properties of graphite surfaces by ion irradiation. The elastic properties were estimated by measuring the frequency characteristics of a cantilever in contact with the graphite surface. This method enabled us to observe the spatial distribution of the elastic properties at nanometer order resolution. Graphite samples were implanted with 3.1 MeV Au ions, each dose was 1 × 1013, 1 × 1014 and 1 × 1015 cm-2. Consequently, we found that the ion-implanted graphite surfaces had fine structures in their elastic properties. The observed structures did not always coincide with the topography. At a dose of 1 × 1013 cm-2, the stiffness of the graphite was the largest, then decreased as the dose increased.
