This paper presents a brief review of experimental and theoretical studies on a three-dimensional heterostructure consisting of vertical carbon nanotubes (CNTs) connected perpendicularly to a graphene layer. This structure can serve as a potential building block for an all-carbon network in energy storage devices and on-chip interconnects. The review highlights reported works on the fabrication and characterization of such a heterostructure, with focus on the effect of the CNT-graphene interface on electrical conduction. While a direct comparison between experiment and theory is not possible at this time, a brief survey of theoretical efforts based on atomic cluster models nonetheless reveals important knowledge about the electronic transport properties of this all-carbon heterostructure.

本文对由垂直连接到石墨烯层的垂直碳纳米管（CNT）构成的三维异质结构的实验和理论研究进行了简要回顾。这种结构可以用作能量存储设备和片上互连中的全碳网络的潜在构建块。审查重点介绍了有关这种异质结构的制造和表征的报道工作，重点是CNT-石墨烯界面对导电的影响。虽然目前尚无法在实验和理论之间进行直接比较，但对基于原子团簇模型的理论工作进行的简短调查仍显示出有关这种全碳异质结构的电子传输性质的重要知识。
