Molecular electronics has opened many field of research and it is still a rather lively subject of investigations across Europe. In this talk coherent and incoherent transport in molecular junctions based on the non-equilibrium Green's function formalism and the density-functional tight-binding method will be discussed . Transport in controlled STM junctions can lead to unexpected transport behaviors due to conformational changes of the molecule induced by the tip. The interplay between interference and electron-vibron scattering in cross-conjugated molecules will be presented [2-4].
