| Abstract: | According to the structural characteristics of atomic coherence in crystal and amorphous Si3N4, a primitive structural unit is constructed with one tegular qnadrahedron N strurmre and a pla nar triangle Si structure, and a model of nanometer- sized scale amorphous Si3N4 is simulated whose structural parameters are in good agreement with experimental work, which will be ed in the future boy of structural and physical properties of amorphous Si3N4 and nanometer-sized amorphous Si3N4. |
