Researchers at the University of Vienna’s Faculty of Physics in collaboration with colleagues from the Oak Ridge National Laboratory in the U.S. have uncovered a non-destructive mechanism to manipulate donor impurities within silicon using focused electron irradiation. In this novel indirect exchange process not one but two neighboring silicon atoms are involved in a coordinated atomic “waltz,” which may open a path for the fabrication of solid-state qubits. The results have been published in the Journal of Physical Chemistry.
