Lithium fluoride (LiF) is an interesting material for spintronic applications and a potential candidate for decoupling single-molecule magnets from metallic substrates. 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.
