3D STM visualization of copper terraces and cobalt impurities

Project description

 

Search for the Kondo Lattice

 

Using the atom manipulation capabilities of the scanning tunneling microscope (STM), we investigate the interactions that result from a square lattice of Kondo impurities. Spectroscopy measurements agree qualitatively with single impurity scattering theory. The agreement suggests that the impurities in the lattice do not interact strongly with one another (as in a Kondo lattice).
