A team of researchers from Consejo Superior de Investigaciones Científicas (CSIC), Delft University (Netherlands) and the Institut Català Nanotechnology has been used electrical currents to move large numbers of atoms, molecules or aggregates in a controlled manner. The work, which combines some other theoretical and experimental simulation calculations, published this week in the journal Small, in nanotechnology.
The researchers placed a thin sheet of metal over a layer of graphene that has received a strong electric current, which was achieved by heating at several hundred degrees, due to the resistance that opposes the movement of current. As a result, the sheet metal is disintegrated into atoms or small aggregates began to move on graphene. "The big surprise was to see that this move proved to be very different depending on the metal used, gold or aluminum," explains Eduardo Hernández, CSIC researcher and project member.
