摘要

本文提出了非对称和对称双栅有机薄膜晶体管（DG-OTFT）的电势模型。该模型严格地从一维泊松方程和电流连续性方程的精确解推导而来。通过保留适当的物理性质，该模型可以准确地描述DG-OTFT的电势和载流子密度分布，并分析了大电压下的近似和非近似分布。此外，本文还基于表面电位方程讨论了DG-OTFT的Ids特性，分析了肩部电流产生的原因。基于该模型的理论计算与实验数据具有较好的一致性，对DG-OTFT技术的发展具有重要的推动作用，并为其在大型电子器件中的应用提供了有价值的见解。

Potential-based model for asymmetric and symmetric double-gate organic thin-film transistors

This paper proposes a potential-based model for asymmetric and symmetric double-gate organic thin-film transistors (DG-OTFT). The model is derived strictly from the accurate solution of one-dimensional Poisson's equation and current continuity equation. By preserving the proper physics, this model can exactly describe the distribution of electric potential and carrier density of DG-OTFT, and analyze the approximate and non-approximate distribution under the large voltage. Moreover, discussing the Ids characteristics of DG-OTFT based on surface potential equation, the causes of shoulder current are also analyzed in this paper. The theoretical calculations based on this model have good consistency with experimental data, playing an important role in promoting the development of DG-OTFT technology and providing valuable insights for its application in large-scale electronic devices.
