The out-diffusion profiles of supersaturated high-temperature substitutional Au and low-temperature substitutional Au were measured by using heat-treatment methods. The profiles of the high-temperature substitutional Au were indicative of a kick-out mechanism, and supersaturated high-temperature substitutional Au was annealed near to the specimen surface. The profiles of low-temperature substitutional Au instead exhibited flat distributions; even after annealing.
