R2R Printed Carbon Nanotube TFT Sheets

Speaker: Patrick Malenfant | Company: National Research Council Canada (NRCC) | Date: 10-11 March 2021 | Full Presentation


This presentation covers our progress in high purity semiconducting single-walled carbon nanotube (sc-SWCNT) enrichment and transistor fabrication via solution based processes. I will highlight our recent progress in understanding sc-SWCNT enrichment using conjugated polymers (isolation of high purity sc-SWCNT), with special consideration given to the effects of solvent parameters and doping on the yield/purity of the final product. Fully printed transistors combining R2R gravure and inkjet-printing will be described as well as our recent progress in realizing “limitless” R2R gravure printed TFT backplanes capable of driving an e-paper display.
