Abstract
We present our findings on organic field-effect transistors (OFETs) that utilize the conjugated copolymer poly[4-(4,4-dihexadecyl-4H-cyclopenta[1,2-b:5,4-b′]-dithiophen-2-yl)alt[1,2,5]thiadiazolo[3,4-c]pyridine] as the active material, with electrodes composed of arrays of carbon nanotubes (CNTs). We employed three types of source and drain electrodes: gold, titanium, and CNT array electrodes with titanium contact pads. A comparison of characteristics of OFETs using these three different electrodes revealed the effectiveness of CNTs in enhancing charge carrier injection for OFETs. The OFETs based on CNT electrodes showed a twofold increase in the drain current and a threefold increase in charge carrier mobility compared to those with gold electrodes.
