Paper Abstract

Luminescent epitaxial β-FeSi2 grains were grown on the Si (111) substrates precoated with Au-layer. These epitaxial β- FeSi2 grains had (101)/(110)-preferred orientation and were constructed with two kinds of triple-domain structure. The Au-Si liquid phase obtained by the Au-Si eutectic reaction contributed to the formation of such β-FeSi2 grains on the Si (111) surface. Clear photoluminescence (PL) spectrum of β-FeSi2 were observed up to 240 K that indicated the formation of high-quality crystals with the low density of the non-radiative recombination center in the grains.
