The manipulation of atoms has reached a new level: Together with teams from Finland and Japan, physicists from the University of Basel were able to place 20 single atoms on a fully insulated surface at room temperature to form the smallest “Swiss cross”, thus taking a big step towards next generation atomic-scale storage devices. The academic journal Nature Communications has published their results.

Ever since the 1990s, physicists have been able to directly control surface structures by moving and positioning single atoms to certain atomic sites. A number of atomic manipulations have previously been demonstrated both on conducting or semi-conducting surfaces mainly under very low temperatures....
