DESCRIPTION:The scanning tunneling microscope allows to build and study nan
 ostructures at a single atom level. It can be further used to explore the 
 ballistic electron transport regime by bringing the tip into contact with 
 single atoms and molecules in a well-defined way. The measurement of quant
 um shot noise in nanoscopic contacts provides additional information on th
 e underlying conduction processes and reveals a spin polarization of the c
 urrent by single Fe and Co atoms between two gold electrodes. The impact o
 f spin-orbit coupling on electron transport is demonstrated using single I
 r atoms on a ferromagnetic substrate\, where large changes of the anisotro
 pic magnetoresistance are observed between the tunneling and the contact r
 egime. In ballistic transport through a Mn-porphyrin molecule we demonstra
 te\, that the voltage drop over the molecular junction moves from the tip-
 molecule gap to the molecule-substrate bond for higher conductances. This 
 strongly modifies the shape of the measured Kondo resonance.\nSpeaker: Ale
