The electronic properties of matter are on the nanometer scale strongly influenced by its local environment. The site dependent electronic properties in composites of semiconducting and metallic matter are at the heart of establishing molecular electronics. Our combined theoretical and experimental investigations comprise firstprinciple calculations, resonant x-ray absorption as well as core-level and valence band photoemission on pristine and potassium intercalated bundles of mixtures of semiconducting and metallic single wall  carbon nanotubes. We present a coherent picture of the archetypical changes in the site selective electronic properties of this tuneable semiconductor/metal hybrid system.
