Solution-processable p-n coaxial nanoheterojunction driven by polymer crystallization |
| 초록 |
Hybrid nanowires (NWs) by fabricated p-type conjugated polymers (CPs) and n-type nanoparticles can provide the continuous charge transport pathway. Due to the competitive assembly of two elements, controlling the location and orientation of the 1D quantum rod (QR) array along the CP NW axis is difficult. Herein, changes in solution processing were used to control the coupling modes of CdSe QRs confined within NWs. The preferred end-to-end QR orientation within the long hybrid NWs is provided by gradual diffusion of a poor solvent at the top layer into a good solvent including CP and QR at the bottom layer. Rapid mixing of good and poor solvents results in the formation of side-by-side QR array in the short hybrid NWs. Coaxial hybrid NWs are affected by competition between CP crystallization and QR dipole-dipole interactions, which affect the QR orientation. This research provides an effective fabrication strategy for p-n hybrid NW with customized performance in optoelectronic devices. |
