제목 Ultra Low-cost N-Doping for Carbon Nanotube Transistors with Baking Soda
초록 Single-walled carbon nanotube (SWNT) is a promising building block for flexible, stretchable, further wearable electronics due to its excellent mechanical and opto-electrical properties and solution processability. However, ambiploar conduction of SWNT results in poor saturation transfer characteristics including high off current, shifted threshold voltage, and large subthreshold swing, because hole and electron are injected into the channel simultaneously in the saturation regime. Furthermore, its intrinsically ambipolar charge transport property is a critical hurdle to realize complementary circuits of SWNTs. Herein, we report the N-doping technique for unipolar SWNT transistors with air stable, the ultra low-cost dopant, a baking soda to improve electrons injection.
