    2020-1-1 · Silicon nitride has the ability to develop a passivating layer on the surface when it reacts with the environment (dry or moist). The bulk of Si 3 N 4 is purely Si–N, while it transits from that phase to Si–N–O in the middle and pure Si–O surface at the surface due to passivation. Hence, the surface chemistry of silicon nitride reveals the composition of charged SiNH 3 +, SiOH 2 +, SiO ...
