| Research Abstract |
We have investigated optical properties of rare-earth doped semiconducting silicides grown by ion implantation to develop silicon-based optoelectronics devices. Rare-earth ion of Er^<3+> was doped into β-FeSi_2 epitaxial films on Si substrate. The Er-doped β-FeSi_2 showed 1.5μm emission which is a wavelength for fiber optics communications.
