Tuning the Interaction Between Spin-Singlet and Spin-Triplet States of Double Donors with Stress
The interaction of the spin-singlet and spin-triplet terms of the 1s(A sub 1)1s(T sub 2) configuration under uniaxial stress, previously reported for Si:Se sup 0, is studied for Si:Te sup 0 where the spin-orbit interaction is much larger. For Si:Te sup 0 spin-triplet states are already observable at zero stress.
