The emission channeling technique was applied to evaluate the lattice location of implanted 59Fe in single-crystalline ZnO. The angular distribution of β- particles emitted by 59Fe was monitored with a position-sensitive electron detector, following 60 keV low dose (2.0×1013 cm-2) room-temperature implantation of the precursor isotope 59Mn. The emission patterns around the [0001], [1102],[1101], and [2113] directions revealed that following annealing at 800 °C, 95(8)% of the Fe atoms occupy ideal substitutional Zn sites with rms displacements of 0.06-0.09 Å.
