Abstract

Organic thin-film transistor (OTFT) has grown significantly and is now an advanced technology. One of the biggest and most favourable electronic device technologies for printable and flexible electronics is the organic thin film transistor. However, designing large-scale integration circuits remains difficult due to device uniformity. Although semiconductor layer technology has advanced, the quality of the dielectric layers is similarly essential. Leakage current and transistor size are the main factors which impact the electronic device. However, leakage current occurs due to the reduction of dielectric material that affects the parameters like threshold voltage, capacitance and transconductance. To overcome the aforementioned drawbacks, the bi-polymer layers based on squid optimization with the dielectric medium is proposed. Bi-polymers such as PEI-EP (polyetherimide–epoxy polymer), POM-H (polyoxymethylene homopolymer) and SiO\({}_{2}\) is utilized as trilayer dielectric material in this proposed method to reduce the leakage current and act as insulator. Squid game optimization is applied to optimally select the dielectric thickness to perform better performance in the device. Electrical measurements such as \(I{-}V\), transfer characteristics, mobility (\(\mu\)) and capacitance (pF) are used to evaluate the performance of the device. The obtained electrical characteristics are mobility as 355 cm\({}^{2}\) V\({}^{-1}\) s\({}^{-1}\) and capacitance value as 7.00 pF are compared with the existing dielectric materials. The experiment shows that the simulation and modelling of the proposed method performs better than the other existing dielectric medium.

基于鱿鱼优化技术的双聚合物层 OTFT 设计与仿真，利用介质增强电气特性

摘要有机薄膜晶体管（OTFT）发展迅速，现已成为一项先进技术。有机薄膜晶体管是可印刷和柔性电子技术中最大和最有利的电子器件技术之一。然而，由于器件的均匀性问题，设计大规模集成电路仍然困难重重。虽然半导体层技术已经取得了进步，但电介质层的质量同样至关重要。泄漏电流和晶体管尺寸是影响电子器件的主要因素。然而，泄漏电流的产生是由于介电材料的减少影响了阈值电压、电容和跨导等参数。为了克服上述缺点，有人提出了基于乌贼优化介质介质的双聚合物层。双聚合物如 PEI-EP（聚醚酰亚胺-环氧聚合物）、POM-H（聚甲醛均聚物）和 SiO\({}_{2}\) 被用作该方法中的三层介电材料，以降低漏电流并充当绝缘体。鱿鱼游戏优化法用于优化选择介电厚度，以提高器件的性能。电学测量如\(I{-}V\)、传输特性、迁移率（\(\mu\)）和电容（pF）被用来评估器件的性能。与现有的电介质材料相比，得到的电特性为迁移率为 355 cm（{}^{2}/）V（{}^{-1}/）s（{}^{-1}/），电容值为 7.00 pF。实验结果表明，建议方法的仿真和建模效果优于其他现有介质材料。
