Abstract

We report a new semiconducting Ge-Si-Fe alloy thin film grown on Si(100) by reactive deposition epitaxy(RDE) using high vacuum evaporation technique. AES and XRD results show that the new alloy can be regarded as a distorted β-FeSi2 with the Ge participation. The direct band gap of the Ge-Si-Fe alloy was determined to be 0.83eV by optical transmission measurement, which means a red shift of band gap compared with that of β-FeSi2 (Eg=0.87eV).
