Jenga chemistry removes defects in a nickelate superconductor (IMAGE)
Caption
To make the superconducting nickelate at top right, SLAC and Stanford scientists chemically removed layers of oxygen atoms from the perovskite material at top left, much like removing sticks from a tower of Jenga blocks. Growing these materials on just the right substrate got rid of defects that stood in the way of discovering the superconductor’s true nature and properties.
