Issue Date: | 2017 | Source: | Applied physics letters, 2017, v. 110, no. 11, 113504, p. 113504-1-113504-5 | Abstract: | We report on low operating voltage thin-film transistors (TFTs) and integrated inverters based on copper(I) thiocyanate (CuSCN) layers processed from solution at low temperature on freestanding plastic foils. As-fabricated coplanar bottom-gate and staggered top-gate TFTs exhibit hole-transporting characteristics with average mobility values of 0.0016 cm(2) V-1 s(-1) and 0.013 cm(2) V-1 s(-1), respectively, current on/off ratio in the range 10(2) -10(4), and maximum operating voltages between -3.5 and -10 V, depending on the gate dielectric employed. The promising TFT characteristics enable fabrication of unipolar NOT gates on flexible free-standing plastic substrates with voltage gain of 3.4 at voltages as low as -3.5V. Importantly, discrete CuSCN transistors and integrated logic inverters remain fully functional even when mechanically bent to a tensile radius of 4mm, demonstrating the potential of the technology for flexible electronics.
