Abstract
The formation of CaSi2 films on Si(111) by molecular-beam epitaxy (MBE) under fast electron irradiation of CaF2 layers is investigated in the article. The mechanisms and regularities of the changes in the structure and elemental composition of the CaF2/CaSi2/Si system under the influence of an electron beam are established in the present contribution, both directly during the CaF2 growth and after the CaF2 film formation. The method of solid-phase extraction (SPE) is proposed with a subsequent Si sputtering during the electron-beam radiation of the CaF2 film, which leads to a decrease in the CaSi2 film surface roughness and defects density.
