摘要：
Semiconducting iron disilicide (beta-FeSi2) was prepared by ion beam synthesis (IBS) in (111)Si P-type by implantation at 440 degreesC of 195 KeV Fe ions with a dose of 2(.)10(17) Fe+/cm(2) followed by annealing in a N-2 atmosphere at 900 degreesC for 4 h. Characterization of samples included Rutherford backscattering spectrometry (RBS), X-ray diffraction (XRD) pole figure, and Raman spectroscopy. A mixture of beta-FeSi2 and alpha-FeSi2 was observed in the as-implanted state. A Photoluminescence (PL) measurement at 12K indicates the luminescence peak at the energy of about 0.81 eV corresponding to the band gap energy of beta-FeSi2 phase.
