  Recent research activities in the field of epitaxial fluoride nano- and heterostructures on silicon will be presented. The structures have been grown and studied in the group Epitaxial Insulators at Ioffe Physico-Technical Institute using reflection high energy electron diffraction (RHEED) and atomic force microscopy (AFM). X-ray diffraction and photoelectron spectroscopy studies have been carried out in close collaboration with a number of other research groups. The following topics will be discussed:

• Initial stages of CaF2 growth on Si(001) and formation of the interface [1,2]
• Specific features of SrF2 growth on Si(001)
• Epitaxial stabilization of metastable phases in MnF2 films on Si
• Growth and properties of fluoride superlattices (CdF2 - CaF2, MnF2 - CaF2) [3-5]
• Formation of Co and Ni epitaxial nanoislands and films on fluoride surfaces
• Unsolved problems and prospects for future studies
