氧化锡稀磁半导体研究进展

ilute magnetic semiconductors are spin electrons that combine charge conductivity with electron spin to make the material possess both ferromagnetic and conductive properties. Finding dilute magnetic semiconductors with excellent performance and a Curie temperature higher than room temperature is a research hotspot in the past ten years. Tin oxide is a wide bandgap n-type oxide semiconductor and has a wide range of applications in gas sensors，transparent electrodes，and photocatalysis. Tin oxide is one of the important research branches of oxide dilute magnetic semiconductors, and transition metal-doped tin oxide systems have achieved room temperature ferromagnetism. The research progress of SnO2-based dilute magnetic semiconductors is discussed in detail.
