Last November Kalff wrote an editorial piece in Nature Nanotechnology: 'The value of the unforeseen'. The reason behind this publication was the discovery that Kalff and his colleagues at the Kavli Institute of Nanoscience stumbled across; an atomic memory. This discovery might even go on to cause a breakthrough in the chip industry. The researchers built a lkB memory by placing a layer of chlorine atoms, a bit like a blanket, over a thin layer of copper and moving the chlorine atoms around. Or rather, moving the holes, because holes had formed here and there in the one-atom-thick layer of chlorine. "We'd made some kind of slider puzzle that we could use to process information," says Kalff.
