The Raman Spectra of α$$ \alpha $$‐ and β$$ \beta $$‐Si3N4 and Si2N2O Determined Experimentally and by Density Functional Theory

ABSTRACT High‐quality Raman spectra of the two silicon nitride polymorphs α$$ \alpha $$‐ and β$$ \beta $$‐Si3N4 as well as of Si2N2O are presented here. This work significantly extends the previously available data on the Raman spectra of all three phases. For α$$ \alpha $$‐Si3N4, a total of 34 Rama...
