When a defect might be beneficial

Rohan Mishra, assistant professor of mechanical engineering & materials science in the McKelvey School of Engineering, led a widespread team of researchers — including at Washington University, at Oak Ridge National Laboratory in Tennessee and at the University of Missouri-Columbia — that studied the structure and properties of the commonly occurring planar defects at the atomic scale, which spans only a few tenths of a nanometer.
