Epitaxial thin films of the semiconducting transition metal silicide, beta-FeSi2, were grown on (001) silicon wafers. The observed matching face relationship is FeSi2(100)/Si(001), with the azimuthal orientation being FeSi2[010]||Si〈110〉. This heteroepitaxial relationship has a common unit mesh of 59 Å2 area, with a mismatch of 2.1%. There is a strong tendency toward island formation within this heteroepitaxial system.
