摘要：

We report on the identification by electron paramagnetic resonance (EPR) of the atomistic and electronic structure of the Te vacancy (V(Te)) in CdTe. The resolved, isotropic hyperfine interaction with the four nearest Cd neighbors, the isotropic g value of g = 2.000+/-0.001, and the long spin-lattice relaxation time serve as a conclusive identification of the F center. From photo-EPR investigations we obtain two threshold energies for the recharging of V(Te). Its electron ionization transition from the neutral to the positive charge state at 1.4 eV determines the energetic level at E(V)+0.2 eV. It acts as a single donor in CdTe.
