This papers reports on the lattice location of rare earth Pr in thin film, single-crystalline hexagonal GaN using the emission channeling technique. The angular distribution of beta particles emitted by the radioactive isotope 143Pr was monitored by a position-sensitive electron detector following 60 keV room temperature implantation and annealing up to 900°C. The emission channeling data provide direct evidence that Pr is thermally stable at substitutional Ga sites.
