Scanning tunneling microscopy STM allows the manipulation of single atoms on top of a surface1 as well as the construction of quantum structures of arbitrary shape. Additionally, the differential conductance, G (V) dI/dV, is proportional to the local density of states LDOS of the surface spot below the tip. 2 Hence, STM can be used to modify and to measure the LDOS.
