摘要

晶体管被应用于各种集成电路(IC)和众多电子设备中。这些集成电路已成为当代系统不可或缺的组成部分。当有机半导体材料构成有源层时,晶体管被称为 "有机晶体管"。通过对这些有机晶体管进行建模和仿真,可以提高器件的各种特性。本研究的重点是模拟基于五碳烯的有机晶体管的不同配置。为了提高器件性能,由五碳烯组成的活性层与 5 纳米和 15 纳米石墨烯耦合。值得注意的是,顶部栅极配置的导通/关断比从 102 增加到 107,同时阈下摆幅从 276 增加到 59 mV/decade。同样,底部栅极配置的导通/关断比从 105 提高到 109,同时阈下摆幅从 108 提高到 59 mV/decade。利用石墨烯作为活性层材料带来了巨大的好处。这些优势包括导通电流提高到 210 mA,亚阈值摆幅降低到 58 mV/decade,导通/关断比显著提高到 1017。

Enhancing device characteristics of pentacene-based organic transistors through graphene integration: A simulation study and performance analysis
Transistors find application within various integrated circuits (ICs) alongside a multitude of electronic devices. These ICs have become integral components in contemporary systems. When organic semiconducting materials constitute the active layer, transistors are termed “organic transistors.” The enhancement of diverse device characteristics is achievable through the modeling and simulation of these organic transistors. This study focuses on the simulation of different configurations of pentacene-based organic transistors. To augment device performance, an active layer comprising pentacene is coupled with 5 and 15 nm graphene. Notably, the top gate configuration yields an increase in ON/OFF ratio from 102 to 107, accompanied by an enhancement in sub-threshold swing from 276 to 59 mV/decade. Similarly, the bottom gate configuration exhibits an ON/OFF ratio improvement from 105 to 109, alongside a sub-threshold swing enhancement from 108 to 59 mV/decade. Leveraging graphene as the active layer material results in substantial benefits. These encompass a heightened on-current of 210 mA, a reduced sub-threshold swing of 58 mV/decade, and a significantly enhanced ON/OFF ratio of 1017.
