In this paper, we have investigated the delay optimization using repeater insertion in folded graphene nanoribbon (FGNR) interconnect systems for different nanometer technology nodes. The mean free path is modeled as a function of GNR width and Fermi energy. The RLC equivalent circuit is modeled for analyzing delay and power for global interconnects. The performance of FGNR is compared to that of multi-layer horizontal graphene nanoribbon (ML-HGNR) and multi-layer vertical graphene nanoribbon (ML-VGNR) interconnects. Our analysis shows that proposed FGNR interconnect with fully diffusive edges can outperform both the ML-HGNR and ML-VGNR interconnects as well as the traditional Cu interconnects by reducing the number of repeaters.

在折叠石墨烯纳米带互连系统中使用中继器插入进行延迟优化

在本文中，我们研究了在不同纳米技术节点的折叠石墨烯纳米带 (FGNR) 互连系统中使用中继器插入的延迟优化。平均自由程被建模为 GNR 宽度和费米能量的函数。该RLC等效电路建模分析延迟和功耗全球互连。将 FGNR 的性能与多层水平石墨烯纳米带 (ML-HGNR) 和多层垂直石墨烯纳米带 (ML-VGNR) 互连的性能进行比较。我们的分析表明，通过减少中继器的数量，提出的具有完全扩散边缘的 FGNR 互连可以优于 ML-HGNR 和 ML-VGNR 互连以及传统的 Cu 互连。
