Abstract / Description:The Hohenberg-Kohn theorem states that the ground state
electron density completely determines the external potential
acting on an electron system. Inspired by this fundamental
theorem, we developed a novel approach to map directly the
electron potential in surface systems: linear response theory
applied to the total electron density as measured with scanning
tunneling microscopy determines the external potential.
Potential imaging is demonstrated for the s-p derived surface
state on Au(111), where the "herringbone" reconstruction
induces a periodic potential modulation, the details of which
are revealed by our technique.
