Molecular bridge: Adsorption and self-assembly of anthrahelicene molecules on an InSb(001) surface is studied with low-temperature scanning probe microscopy (see picture). Molecules adsorb with the helical axis almost perpendicular to the substrate, decorating atomic step edges at lower coverage. At higher coverage, islands with a quasi-hexagonal ordering are formed. Interference between tunneling through the molecular layer and directly through space is reported.
