Elucidating the influence of native defects on electrical and optical properties in semiconducting oxides: An experimental and theoretical investigation

نویسندگان

چکیده

Defect engineering using self-doping or creating vacancies in polycrystalline oxide based materials has profound influence on optical absorption, UV photo detection, and electrical switching. However, defects induced semiconducting devices show enhancement detection photosensitivity, hence still remain interesting the field of optoelectronics. In this study, defect is discussed along with their roles optoelectronic device-based applications. Theoretical investigations have been done for identifying states by performing first-principles electronic structure calculations, employing density-functional theory. Particularly, work we focused probing defect-induced changes processes means experimental as well computational investigations. Hence, systematic measurements switching, charge density, photocurrent defect-rich samples performed. Our results suggest that can lead to properties such photocurrent, switching speed, absorption etc. devices.
