Enhanced Charge Carrier Mobility in Field-Effect Transistors Made of Soluble π-Conjugated Polymer Achieved by Macroscopic Chain Alignment |
초록 |
The newly synthesized PTDPP-DTTE exhibited high crystallinity in a film state following thermal treatment, with the corresponding TFT device exhibiting a high carrier mobility. In this study, we then applied two extrinsic treatments to the PTDPP-DTTE polymer, solution shearing (SS) and template-guided solution shearing (TGSS) in order to increase the anisotropy of the polymer chains in order to increase the carrier mobility in the shearing direction. Field-effect transistors composed of micro-patterned prism arrays of PTDPP-DTTE displayed the highest mobility of approximately 7.3 cm2 V-1 s-1, which is higher than that obtained from TFTs treated under the solution-shearing process. Therefore, the TGSS method is recognized as a very promising method to increase the performance of electronic devices requiring high anisotropy of the conjugated molecules and polymers. |
