Two-dimensional metal films show distinctly different behaviour compared to their three-dimensional cousins. Metals are no van der Waals materials, however, 2D films can be prepared via confinement epitaxy by intercalating metals between epitaxial graphene and the hosting SiC crystal. Here, we explore the fascinating properties of D gallium and indium that include plasmonic resonances and superconducting behaviour by a combination of spectroscopic imaging ellipsometry, scanning probe methods and Raman spectroscopy.
