‘Artificial atom’ created in graphene
In a tiny #quantum prison, electrons behave quite differently as compared to their counterparts in free space. They can only occupy discrete energy levels, much like the electrons in an atom – for this reason, such electron prisons are often called ” #artificialatoms “. Artificial atoms may also feature properties beyond those of conventional ones, with the potential for many applications for example in quantum computing. Such additional properties have now been shown for artificial atoms in the carbon material #graphene. The results have been published in the journal Nano Letters (“Electrostatically Confined Monolayer Graphene Quantum Dots with Orbital and Valley Splittings”), the project was a collaboration of scientists from TU Wien (Vienna, Austria), RWTH Aachen (Germany) and the University of Manchester (GB).
