摘要：

Low-voltage Zn-doped CuI thin film transistors (TFTs) gated by chitosan dielectric were fabricated at a low temperature. The Zn-doped CuI TFT exhibited a more superior on/off current ratio than CuI TFT due to the substitution or supplementation of copper vacancies by Zn ions. The Zn-doped CuI films were characterized by scanning electron microscope, X-ray diffraction, and X-ray photoelectron spectroscopy. The Zn-doped CuI TFTs exhibited an on/off current ratio of 1.58 x 10(4), a subthreshold swing of 70 mV/decade, and a field effect mobility of 0.40 cm(2)V(-1)s(-1), demonstrating good operational stability. Due to the electric-double-layer (EDL) effect and high specific capacitance (17.3 mu F/cm(2)) of chitosan gate dielectric, Zn-doped CuI TFT operates at a voltage below 2 V. The threshold voltage is 0.2 V. In particular, we have prepared Zn-doped CuI TFTs with two in-plane gates and NOR logic operation is implemented on such TFTs. In addition, using the ion relaxation effect and EDL effect of chitosan film, a simple pain neuron simulation is realized on such a p-type TFTs for the first time through the bottom gate to regulate the carrier transport of the channel. This p-type device has promising applications in low-cost electronic devices, complementary electronic circuit, and biosensors.
