论文摘要
在这项研究中,我们报告了用于定义石墨烯场现场效应晶体管(GFET)的模块化紧凑型建模技术的进展,该技术能够对基于GFET的任意集成电路进行电气分析。包含主要物理原理的一组主要模型定义了DC,瞬态(时域),AC(频域)和噪声(频域)分析下的理想GFET响应。其他一组二级模型说明了GFET非理想性,例如外部,短渠道,捕获/detrapping/detrapping-,自加热 - 和非Quasi静态效应,在静态和/或动态操作下可能会产生重大影响。在设备和电路水平上,在相关操作条件的模拟输出和实验数据之间均显示出显着的一致性。此外,我们还提供了GFET建模技术对更高技术准备水平的规模的挑战的观点,同时在制造技术组,建模组和电路设计师之间绘制了协作方案。
In this study, we report the progress made towards the definition of a modular compact modeling technology for graphene field-effect transistors (GFET) that enables the electrical analysis of arbitrary GFET-based integrated circuits. A set of primary models embracing the main physical principles defines the ideal GFET response under DC, transient (time domain), AC (frequency domain), and noise (frequency domain) analysis. Other set of secondary models accounts for the GFET non-idealities, such as extrinsic-, short-channel-, trapping/detrapping-, self-heating-, and non-quasi static-effects, which could have a significant impact under static and/or dynamic operation. At both device and circuit levels, significant consistency is demonstrated between the simulation output and experimental data for relevant operating conditions. Additionally, we provide a perspective of the challenges during the scale up of the GFET modeling technology towards higher technology readiness levels while drawing a collaborative scenario among fabrication technology groups, modeling groups, and circuit designers.
