As a model surface, graphite slides were treated by pure nitrogen gas plasma for different periods (15 sec - 5 min). These samples were kept in air or under argon atmosphere in sealed holders. STM images were obtained at constant current mode. Results showed that both the number and the size of clusters formed by plasma deposition increased with exposure time.
