| Outline of Final Research Achievements |
In this study, we examined the properties of transition metal mononitrides (ScN - CuN) from the viewpoint of the difference from corresponding oxides, and discussed how the characteristics of transition metal elements appears especially in the stability of the mononitrides. The approaches were made from both calculations and experiments. The results of the first principles calculations for the nitrides of Ni to Cu revealed that the influence of the energy of the anti-bonding orbitals are very important to understand the trend of the stability. The main concept of the present research will contribute to the enhancement of the utilization of first principle calculation by experimental chemists to understand the properties of solids using their chemical insights.
