Abstract: The lattice location of ion implanted antimony in zinc oxide has been determined by means of beta(-) emission channeling from the radioactive Sb-124 isotope. Following 30 keV implantation of Sb-124 into a single-crystalline ZnO sample to a fluence of 1x10(14) cm(-2), the angular-dependent emission rate of beta(-) particles around several crystallographic directions was measured with a position-sensitive Si detector. The majority of Sb was found to occupy Zn sites, with the possible fraction on O sites being at maximum 5%-6%.
