Abstract

The Emission Channeling technique has been used to study the annealing behavior of ZnTe implanted with different doses of Cd. 111mCd ions of 60 keV energy were implanted at 100 K into a single crystal sample at the on-line isotope separator, ISOLDE, at CERN. Emission channeling measurements were performed along the 〈1 0 0〉 and 〈1 1 0〉 axial directions on the conversion electrons emitted in the 111mCd decay. The temperature at which practically complete lattice recovery is achieved in the neighbourhood of the implanted probes, with the probes on substitutional sites, was found to depend strongly on implantation dose. For an implantation dose of 1.3 × 10 13Cd/cm 2 essentially full recovery of the lattice occurred at 500 K, while for a dose of 1.8 × 10 13Cd/cm 2 lattice recovery was achieved at 550 K. At a dose of 2.3 × 10 13Cd/cm 2 no recovery was observed up to a temperature of 550 K.
