We present a detailed investigation of the growth kinetics of aluminium-related shallow thermal donors: the K-donors. Constraints for the diffusion mechanism of oxygen in silicon at temperatures ≈ 470°C are found. A large entropy of the K-donors is considered as a possible explanation of high diffusivities and interaction radii found for the generation of the K-donors. |
