Abstract
Electron localization in different systems has been a topic of study for over a half of a century; polaron formation in the solid state and electron solvation by liquids are just two examples. Structureless by itself but interacting strongly with the condensed phase environment, an electron is often utilized as a probe of its local microscopic structure. Despite that, there are few attempts to access the shape of a localized electronic wave function directly from an experiment. Here, we report an elegant way of estimating the electron localization size parallel to a two-dimensional metal/adsorbate interface by using time and angle resolved two-photon photoemission (TAR TPPE).
