    Atomic and electronic structures of the CaF2/Si(111) interface and the desorption mechanism of F from epitaxial CaF2(111) films produced by electron irradiation have been studied by low-energy electron energy loss spectroscopy (EELS). The interface is formed by the desorption of F and becomes metallic. The F at the surface of epitaxial CaF2(111) films desorbs by electron irradiation, and the surface after F-desorption becomes metallic. The metallic surface reverts to the bulk electronic state before electron irradiation by annealing at about 400°C.
