It is shown that LiF(100) films with the electronic properties of cleaved bulk LiF crystals can be grown epitaxially on Ge(100). These include an exceptionally large, negative electron affinity of -2.7 eV, which leads to intense photoemission at zero kinetic energy. The valence band offset ranges from 7.3-7.6 eV.
