An overview of the evolution of defect theory and a discussion of ongoing developments is presented in the article. For semiconductors, all their electrical and optical properties are determined by the type and concentration of defects they contain. Sufficient defect control could once be achieved by 'brute force' methods, such as long high-temperature anneals to precipitate excess unwanted impurities away from the active part of a device.
