WitrynaIn a lattice, when an impurity atom has a tetrahedral or octahedral hole into atoms, then an interstitial impurity defect occurs. It is a type of point defect. It is very small and can be fixed into a tetrahedral or octahedral hole in a lattice. For example: Carbon atoms with steel that contain iron are attached to interstitial impurities. WitrynaTherefore, in the discussions below, the word “impurity” may be understood as representing either impurity or point defect, unless specifically stated otherwise. In the literature, impurities are typically classified into two categories: “shallow” and “deep”.
