defectengineered
Defectengineered refers to materials or devices in which defects are deliberately introduced or manipulated to achieve specific properties or performance. It is a way of describing defect engineering, where controlled imperfections are used as functional features rather than unwanted flaws.
Defects involved in defectengineering can be point defects such as vacancies, interstitials, and dopant atoms; extended
Common methods to achieve defectengineering include ion implantation and irradiation, chemical doping, alloying, mechanical deformation, thermal
Applications span several fields. In semiconductors, defects tailor carrier concentration and trap states; in catalysis, defect
Characterization relies on electron microscopy, X-ray and spectroscopy methods, and defect-specific techniques like positron annihilation or
