Micropatterned Single-Walled Carbon Nanotube Electrodes for Use in High-Performance Transistors and Inverters |
| 초록 |
We demonstrated the solution-processed single-walled carbon nanotube source−drain electrodes. The high-resolution SWNT electrode patterning began with the formation of highly uniform SWNT thin films on a hydrophobic silanized substrate. The SWNT source−drain patterns were then formed by modulating the interfacial energies of the prepatterned elastomeric mold and the SWNT thin film. The SWNT films were subsequently selectively delaminated using a rubber mold. The patterned SWNTs could be used as the source−drain electrodes for field-effect transistors. The n- and p-type devices exhibited good and exactly matched electrical performances, with a field-effect mobility of around 0.15cm2V−1s−1 and an ON/OFF current ratio exceeding 106. The single electrode material was used for both the n and p channels, permitting the successful fabrication of a high-performance complementary inverter by connecting a p-type pentacene FET to an n-type PTCDI-C8 FET. |
