Lithium fluoride (LiF) is an interesting material for spintronic applications[1] and a potential candidate for decoupling single-molecule magnets from metallic substrates.[2] We have investigated the growth and morphology of LiF deposited onto the Ag(100) surface in the monolayer regime under different conditions. Scanning tunneling microscopy, low energy electron diffraction and polarized X-ray absorption spectroscopy reveal that LiF exhibits epitaxial Volmer-Weber type growth. When the substrate is held at room temperature during growth, anisotropic and strained dendrites form, while at 500 K LiF self-assembles into more relaxed square islands displaying a Moiré pattern.
