Keywords: single-walled carbon nanotube (SWCNT), spray coating, Al/SWCNT bilayer electrodes

SWCNTs have various bandgaps so that they show metal as well as semiconductor characteristic. However, it is difficult to separate the metallic and the semi-conducting SWCNTs. Also, the high contact resistance at the interface between SWCNTs and the channel causes loss of carrier mobility. In this study, we fabricated the Al/SWCNT bilayer electrodes and applied this structure to fabricated transparent thin film transistor (TTFT) for reducing the contact resistance.To evaluate the contact resistance between the In2O3 channel and the SWCNTs electrodes, Transmission Line Method (TLM) was applied and electrical properties were measured.Furthermore, optical property was measured by ultraviolet-visible spectrophotometer.
