Sr2MgTi6N2O11
Sr2MgTi6N2O11 is a semiconducting oxynitride compound containing strontium, magnesium, and titanium that is primarily studied for its complex structural properties.
About Sr2MgTi6N2O11
Sr2MgTi6N2O11 is a complex quaternary oxynitride featuring a combination of alkaline earth, transition metal, and pnictogen elements. Its semiconducting electronic character makes it a subject of interest for researchers investigating the intersection of oxide and nitride chemistry for optoelectronic applications.
While this material exhibits a rich variety of reported structural configurations, it is characterized as being thermodynamically metastable. This suggests that its synthesis requires precise control over processing conditions to stabilize the desired phase for fundamental study.
Key Properties
Cross-validated computational properties for Sr2MgTi6N2O11, aggregated across 2 databases.
