Abstract:Scanning tunneling microscopy (STM) has been used to study polydiacetylene nanowires, a candidate material for molecular electronic interconnects. STM analysis across different voltages shows that the substrate material contributes to hole doping in the nanowires. Changing the substrate material causes a substantial change in the apparent height of the nanowires in STM images, revealing a previouslyoverlooked dependence of the electronic structure upon the substrate electrode material. Polydiacetylene nanowire… Show more
