• order regular approximation (ZORA) to the Dirac equation was used to account for relativistic effects in the electrodes. Each molecule is connected to two pyramidal gold electrodes consisting of 55 atoms each and initially separated by a gap of 0.7 nm (center-to-center distance between the two gold

• adatoms is 0.94 nm). The geometry was converged to energy changes of less than 10−3 hartree, energy gradients of less than 10−3 hartree/Å maximum and 6.7 · 10−4 hartree/Å RMS. We then start to separate the gold electrodes in steps of 4 pm and for each new gap size we relax the geometry of the molecule and

We observe a close similarity between the LUMO from Method 1 and the LUMO+1 from Method 2, as

Together with the sputtering processes it leads to surface roughening and the development of a periodic pattern. Although the sputtering
