Abstract for Presentation

 Carbon nanotube TFTs for display applications


Single-walled carbon nanotubes (CNTs) are envisioned as promising candidate for both high-performance transistors and thin film transistors (TFTs), which will impact the beyond silicon complementary metal oxide semiconductor (CMOS) technology and the future macroelectronics. It is still a great challenge for the CNT-based CMOS technology to compete with the well-established Si technology. However, the CNT-TFT technology develops very fast in recent years, which are expected to demonstrate its commercial value soon in the macroelectronics area.   
CNT-TFTs have shown high mobility, high on/off ratio with high on-current, which performance can surpass the current TFT technologies being used in the flat panel display industry. Moreover, the fabrication process is facile, reliable, scalable to large area, and compatible with the current TFT manufacturing process. Therefore, a lot of research efforts have been paid to the display applications of CNT-TFTs.  
In this talk, we will report our work on the CNT-TFT technology, including the fabrication and chirality control of high purity semiconducting single-walled carbon nanotube materials, large area uniform and density controllable CNT thin films, large scale CNT-TFTs fabrication, performance optimization and their application for flat panel display.
