Observation of spin triplet states for double donors in silicon.
01 January 1986
By the application of uniaxial stress an allowed optical transition of chalcogen donors in silicon can be brought into near-resonance with a forbidden transition. If the interaction coupling the two transitions is strong enough both transitions will become visible in absorption. We report here the first study of spin triplet states of double donors and our results indicate that many-electron effects are substantial in these systems.
