In recent years, single crystalline ultra thin metallic films have been studied in transport, magnetic and spectroscopic measurements, many of their properties show dramatic dependence on the exact thickness of the film. In this talk I will present scanning tunneling microscopy/spectroscopy(STM/S) investigations of ultra thin Pb films, which revealed quantum oscillation of work function and superconductivity as function of film thinness. Furthermore, 2ML epitaxial Pb films, the ultimate two-dimensional regime where the underline electrons are two dimensional in the sense that their lateral motion is frozen into a single quantum channel, exhibit several interesting features in the superconductivity.
