Abstract

The behaviour of Fe in Si has been studied by Fe⁵⁹ radioactive tracers method and ESR measurement of Fe-interstitial resonant line. The major quantity of Fe⁵⁹ precipitates on the specimens’ surfaces (6 × 10¹⁶ cm⁻³).
The interstitial mechanism of iron diffusion in Si is proposed. The concentration of diffused-in Fe⁵⁹ depends on the concentration of native iron which is present in almost all Si crystals. At room temperature, unstable Fe interstitials do not interact with self-interstitials and vacancies produced by Co⁶⁰ gamma rays.
