Origin of Change of Plasmon Energy

Table 1199. Origin of change of plasmon energy.

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
