Description	The surface structure of epitaxial β-FeSi2(100) thin film grown on Si(001) was analyzed using the quantitative low-energy electron diffraction intensity-voltage (LEED I-V) method, ab initio density functional theory (DFT) calculations, and scanning tunneling microscopy (STM). The iron-silicide film truncation and atomic surface structure were determined by LEED I-V method. Significant atomic relaxations within the topmost surface layers were revealed by the LEED I-V method and confirmed by DFT. The simulated STM patterns from the best-fit model agree well with the measured STM images on the β-FeSi2(100)/Si(001)-p(2 2) surface. Electronic band structure analysis of the bulk and epitaxial β-FeSi2(100) was carried out. Surface electronic states were identified by a partial k-resolved atomic-orbital based local density-of-state analysis.
