Abstract

A clear PL spectrum was observed from β-FeSi 2 grains on gold (Au)-coated (100)Si substrates, and indicated the formation of crystal with the same high quality level as the β-FeSi 2 on a copper (Cu)-coated Si substrate. Moreover, the temperature dependence of photoluminescence peak intensities showed lower density of the nonradiative recombination center in β-FeSi 2 grains on Au-coated Si substrates than that of β-FeSi 2 film on Cu-coated Si. Au was not detected in β-FeSi 2 grains by STEM-EDX observation, while Cu was observed in the grains and grain boundaries of β-FeSi 2 and rolled as non-radiative recombination center.
