Voltage Control of Exchange Coupling in Phosphorus Doped Silicon
C. J. Wellard, L. C. L Hollenberg, L. M. Kettle +1
Motivated by applications to quantum computer architectures we study the change in the exchange interaction between neighbouring phosphorus donor electrons in silicon due to the ap…

Effects of J-gate potential and interfaces on donor exchange coupling in the Kane quantum computer architecture
L. M. Kettle, H. -S. Goan, Sean C. Smith +2
We calculate the electron exchange coupling for a phosphorus donor pair in silicon perturbed by a J-gate potential and the boundary effects of the silicon host geometry. In additio…
