Strontium stannate (SrSnO3) (IMAGE) University of Minnesota Caption While studying a thin-film material called strontium stannate (SrSnO3), University of Minnesota researchers noticed the surprising formation of checkerboard patterns at the nano scale similar to structures fabricated in costly, multistep processes. Their results show the realistic possibility of designing similar self-assembled structures with wide applications in materials for electronics and optical devices.
