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.
