Notes:
We investigated the redistribution of an atomic-layer-doped (ALD) Sb in Si upon post-growth annealing using secondary-ion mass spectrometry (SIMS). Shoulder development in the SIMS profile was observed after annealing over 710 °C, suggesting the presence of two different diffusion mechanisms. Diffusivities were found to be in excess of the bulk diffusivity and were concentration dependent above n(Sb)≈5×1017 cm−3. Asymmetric diffusion of ALD Sb in the epitaxial layers and Sb segregation at the oxide interface were also observed.
