Implantation site of rare earths in single-crystalline ZnO
The lattice location of rare earth Er in single-crystalline hexagonal ZnO was studied by means of the emission channeling technique. Following 60-keV room-temperature implantation of the precursor isotope Tm at doses of 1.3−2.8×10 cm and annealing up to 900°C, the angular distribution of conversion electrons emitted by the radioactive isotope Er was measured by a position-sensitive electron det...
متن کاملLattice location and stability of implanted Cu in ZnO
The lattice location of copper in single-crystalline zinc oxide was studied by means of the emission channeling technique. Following 60-keV room-temperature implantation at a fluence of 2.3310 cm, the angular distribution of b particles emitted by the radioactive isotope Cu was measured by a position-sensitive detector. The b emission patterns give direct evidence that in the as-implanted state...

متن کاملPhotoluminescence and damage recovery studies in Fe-implanted ZnO single crystals
We report Fe-related emission in ion-implanted ZnO single crystals. Iron ions were implanted at room temperature with 100 keV and a fluence of 1310 Fe/cm, and were submitted to annealing treatments in vacuum and in air. After implantation, the damage raises the minimum yield (xmin) from 2% to 50%. Annealing in an oxidizing atmosphere leads to a reduction of the implantation damage, which is ful...
متن کاملLATTICE LOCATION AND OPTICAL ACTIVATION OF RARE EARTH IMPLANTED GaN
This paper reviews the current knowledge on rare earths (REs) implanted into GaN with a special focus on their lattice location and on the optical activation by means of thermal annealing. While emission channeling experiments have given information on the lattice location of rare earths following low-dose (≈10 cm) implantation, both in the asimplanted state and after annealing up to 900°C, the...
