WitrynaImpurities. Impurities can be classified as interstitial or substitutional. An interstitial impurity A point defect that results when an impurity atom occupies an octahedral hole or a tetrahedral hole in the lattice between atoms. is usually a smaller atom (typically about 45% smaller than the host) that can fit into the octahedral or tetrahedral holes in … WitrynaTable 9.5); also the binding energy of Ti-O and Ti-N is smaller than that of Si-O (see [17] p. F 222 ff). Let us also emphasize that minor oxygen impurities of about 1 wt. % stabilize the α-Si 3 N 4 phase [18], and cause the amorphization of nc-Si [19]. 3.2.
