Doped photoresponsive nanodevices. A thiol end-capped and iodine-doped sexithiophene disulfide polymer is used to bridge nanogap gold electrodes via an in-situ oxidation, doping, and self-assembly method. Temperature-dependent semiconducting and photoresponsive nanodevices are formed and Coulomb-blockade phenomena are observed in these organic molecule-based nanodevices.
