Abstract
At the RI-beam facility of the RIKEN, 57Mn/57Fe isotopes are separated and implanted into n-type FZ-Si (6Ã1016Â As/cm3), and subsequently the atomic jump processes of 57Fe in the Si matrix are observed by Mössbauer spectroscopy on a time scale of 100Â ns between 330 and 1200Â K. The spectra consist of two components due to “interstitial Fe” and “substitutional Fe”, both of which yield the same isomer shifts as those reported in p-type Si, showing long-range diffusion with increasing temperature. The spectra are compared with those simulated from a theoretical model.
