| Outline of Final Research Achievements |
Relationship between the structure of amorphous carbon and its physical property was investigated by using molecular dynamics simulation. New potential model to accurately represent amorphous carbon material was developed. By this potential model, structure phase transition from the graphite to diamond due to high pressure and the formation process of diamond like carbon by plasma chemical vapor deposition were successfully reproduced by molecular dynamics. Method to classify amorphous carbon structures was investigated. Consequently, the elastic modulus of amorphous carbon increases proportionally to the number density of the carbon atoms with four covalent bonds with the other carbon atoms, and amorphous carbon structure can be classified into three kinds of structures. Furthermore, the MD-MC hybrid simulation method was newly developed in advance research, and then it succeeded in performing the world’s first simulation of the formation process of tungsten fuzzy nanostructure.
