Electrical Transport through Single Nanowires of Dialkyl Perylene Diimide |
| 초록 |
We investigated charge transport through individual single-crystalline PTCDI-C5 and PTCDI-C8 nanowires prepared by a solution-phase self-assembly method. Temperature-dependent mobility measurements revealed distinct transport characteristics in the two types of nanowires. The PTCDI-C8 nanowire having shorter intermolecular distances exhibited a transition in the electrical transport from a thermally activated process to a band-like transport with increasing temperature. In contrast, the transport through the PTCDI-C5 nanowire was mostly determined by thermally activated behavior. The observation of band-like transport in the PTCDI-C8 nanowire was attributed to the small number of charge traps. Meanwhile, band-like transport was hardly attainable in the PTCDI-C5 nanowire due to the presence of a large number of charge traps. Unlike the case of the single-crystal PTCDI-C8 nanowire, thin films of PTCDI-C8 contained significant numbers of exponentially distributed charge traps. |
