As the CNT channel has a network structure, only a compact area of ion gel is required to make the capacitive coupling effect viable, unlike the planar channels of previously reported transistors that required a substantially larger area of ion gel dielectric layer to induce the coupling effect. The capacitively coupled CNT TFTs possess superlative electrical characteristics such as high carrier mobilities (42.0 cm(2) (Vs)(-1) for holes and 59.1 cm(2) (Vs)(-1) for electrons), steep subthreshold swings (160 mV dec(-1) for holes and 100 mV dec(-1) for electrons), and low gate leakage currents (<1 nA). These devices can be further integrated to form complex logic circuits on flexible substrates with high mechanical resilience. The layered geometry of the device coupled with scalable solution-based fabrication has significant potential for large-scale flexible electronics.
