Abstract:
An optical material comprising:crystalline silicon having an interior and a surface; and FexSi2 in the interior of the crystalline silicon or on the surface of the crystalline silicon, wherein the FexSi2 is in a form selected from the group consisting of dots, islands, and a film; the FexSi2 has a symmetrical monoclinic crystalline structure belonging to the P21/c space group and corresponding to a deformed structure of &bgr;-FeSi2 generated by heteroepitaxial stress between the {110} plane of the FexSi2 and the {111} plane of the crystalline silicon; the FexSi2 has a thickness in a range of from 5 to 2,000 Ã¥; and 0.85&lE;x&lE;1.1.
