摘要：
We explore the electronic structure, as well as the magnetic and optical properties of (Fe, F) and defects (O vacancy noted as VO and Sn vacancy noted as VSn) co-doped SnO2 systems within the GGA + U framework. The results indicate that the co-doped systems (especially the Sn15FeFO30 system in the presence of VO) exhibit ferromagnetism and have the lower formation energy than other doped systems. The bandgap of the co-doped system is diminished and the optical absorption edge is red-shifted. Moreover, the (Fe, F) co-doped system has a high optical transmittance. This study offers an important guide for modification by co-doping to improve the magnetic optical performance of SnO2-TCO films. © 2022 Elsevier B.V.
