摘要：

根据石墨烯有无碳源的实际生长方式，构建了4种石墨烯/碳纳米管T型复合三维结构采用结合密度泛函理论与非平衡格林函数的计算方法对这4种结构的电子输运特性进行了研究．首先在ATK软件中构建双探针模型并进行了结构优化，然后对这四种结构的透射图谱和电子态密度谱线进行了仿真分析．研究结果可为基于碳纳米材料三维互连线结构的相关研究提供参考．

Abstract:

According to the actual growth way of graphene presence of the carbon source, four kinds of 3d grapheme-carbon nanotubes composite T structure are built, and their electron transport properties studied by combining density functional theory and the non-equilibrium green's function method. First the double probe model is built and the structure optimization is designed in ATK software, and then their transmission spectrums and electronic state density spectrum lines are analyzed. These research results can provide the reference for the 3d interconnect based on carbon nanomaterials.

Key words: graphene, carbon nanotube, 3d internation, electron transport properties
