Oliver Rader (BESSY, Berlin):

What nanostructures tell about the electronic structure of their substrates

Angle-resolved photoemission delivers information about the electronic structure, in particular it is the only method to measure E(k) dispersions of occupied electronic states of solids and nanostructures.
 
Examples will be presented where nanostructures deliver mainly information about the electronic structure of the substrate. One such example are single atomic chains of Gd atoms on the W(110) surface which form an elastic superlattice there. Another one are two-dimensional Ag films on Ni(111) the quantum size effects of which give insight into the electronic structure of Ni in its ground state.
