| Summary: | Due to their unique structure and excellent properties, single-walled carbon nanotubes (SWNTs) have great potential on nanoelectronics applications. Now it is still difficult to control the electronic type of SWNTs by direct synthesis techniques, and post-synthetic treatment is required to obtain pure semiconducting SWNTs for FET devices. The post-synthetic separation/conversion methods can be roughly divided into two groups. One group is solution-based separation method. The other one is on-chip based separation or conversion process. Comparing with the solution-based methods, on-chip based separations or conversions are more simple and direct due to not involving purification, surfactant and sonication issues, which can degrade performance of SWNT-based FET. Thus, this thesis focuses on developing on-chip based separation or conversion technologies to obtain SWNT FET with good performance. |
