摘要：
We have grown highly [100]-oriented beta-FeSi2 Continuous films on lattice-matched Si(001) surfaces using Si0.7Ge0.3 layers by molecular beam epitaxy (MBE). The beta-FeSi2 films grown on the lattice-matched Si(001) did not aggregate even when it was grown at temperatures above 600degreesC. The omega-scan full width at half maximum of the beta-FeSi2(800) peak was smaller than that of the film grown on Si(001) over the entire growth temperature ranging from 500 to 720degreesC. X-ray diffraction pole figure measurements revealed that a [100]-oriented beta-FeSi2 template layer is necessary to obtain [100]-oriented beta-FeSi2 films by MBE even on the lattice-matched Si(001).
