Manipulation of the Kondo Effect via Two-Dimensional Molecular Assembly

Manipulation of the Kondo Effect via Two-Dimensional Molecular Assembly

We report the manipulation of a Kondo resonance originating from the spin-electron interactions between a two-dimensional molecular assembly of TBrPP-Co molecules and a Cu(111) surface at 4.6 K. By manipulating nearest-neighbor molecules with a scanning tunneling microscope tip we are able to tune the spin-electron coupling of the center molecule …
