Description
SixMn1-x diluted magnetic semiconductors (DMS) were prepared by implanting 200 keV Mn ions into p-Si (100) wafers and annealing them at 600 degree C,700 degree C, 800 degree C or 900 degree C under N2 atmosphere. The samples were studied by means of synchrotron radiation X-ray diffraction at SSRF (Shanghai Synchrotron Radiation Facility). It was found that the Mn implantation and thermal annealing resulted in appearance of silicon crystalline particles. At increasing annealing temperatures, the number of Mn atoms on interstitial sites decreased gradually while those on substitution sites increased. And the crystal lattice expanded, too. Interaction of Mn atoms between interstitial and substitution sites increased the ferromagnetism of SixMn1-x DMS samples. (authors)
