Abstract
Using spatially resolved energy-loss spectroscopy, electron diffractio n, and He+-ion channeling we have observed the evolution of alpha-Fe d isilicide layers from primary crystallographically badly defined FeSi2 precipitates with increasing Fe dose in as-implanted specimens at con stant target temperature. Increasing the Fe+ dose transforms secondary metallic alpha-FeSi2 first into semiconducting beta-FeSi2 and then in to FeSi. Elevated target temperature at constant dose also causes tran sformation of the secondary alpha-FeSi2 into beta-phase. Results are i nterpreted in terms of beam induced crystallisation.
