| Materials |
Energy change |
Mechanisms |
| SiNx with a smaller x |
Decrease |
Increase of the Si–Si bond concentration |
| SiOx with a smaller x |
Decrease |
Increase of the Si–Si bond concentration |
| Transition layer at Si3N4/SiO2 interface |
Decrease |
Presence of Si–Si bonds at the interface due to Si-rich SiOxNy |
| BeNx with a larger x |
Increase |
Due to higher density of electronic states in the valence band for the nitride phase in relation to the metallic one |
