Rutherford backscattering and ion channeling-axial scans have been used to study lattice sites for several impurities implanted into A12O3. The case of Ga implanted in A12O3 is discussed and is shown to be substitutional on the Al sublattice. Additionally, the use of this technique in the study of precipitates in A12O3 is discussed with reference to Fe implanted A12O3 which was annealed in either oxygen or hydrogen.
