Abstract/OtherAbstract:
Electric-dipole spin resonance of the deep acceptor Zn(-)(S) in Si reveals close gamma(8) and gamma(7) ground states with zero-field separation of only 0.31 meV as compared to the 43 meV of the two valence bands. With Lande's formula for the g factors of a 2T2 state split by spin-orbit interaction into gamma(8) and gamma(7) this nearness can be interpreted as strong quenching of the orbital moment. The observed dependence on the Zn isotopic mass indicates a dynamic contribution of the acceptor atom to the electronic state as is expected for a Jahn-Teller effect.
