## Description

- description: The atomistic interface structure between β-FeSi2 and Si substrate
    was investigated by cross-sectional scanning transmission electron microscopy
    and density functional theory calculations (DFT). A high quality single crystalline
    β-FeSi2 film was epitaxialy grown on Si(001) substrate. We demonstrate that the
    β-FeSi2(100) plane is bonded to the Si(001) plane with two Si dimers per unit
    cell. With such interface structure, DFT band calculations reveal that metallic
    electronic states are localized at the interface. This finding implies the presence
    of two dimensional electronic states at the interface of β-FeSi2/Si(001),
