Witryna20 sty 2015 · Example 1: removal of an oxygen atom from a ceramic oxide. this results in a vacancy with a charge of two and two electrons in the conduction band. Example 2: addition of extra oxygen in in terstitial site. the defect site in this case acts as an acceptor, and two holes are created in the valence band. M a O b. WitrynaTypes of defects. There are two main types of defects in solids: Line defect; Point defect; Line defect. In such defects, the solid expands above the microscopic region in a row of a crystal lattice. Point defect.
