摘要:

富勒烯功能化碳纳米管- NanoBuds -形成一类新型的杂化碳材料,与原始组分相比具有许多优点。在这里,我们报告了这些化合物的电子输运性质的理论研究。我们使用从头算技术和紧束缚计算来说明这些材料的传输特性,并给出物理参数来解释数值结果。具体而言,在费米能量以上,我们发现由于在结构的某些区域中的局域态而导致电子透射的强烈减少,而在费米能量以下,所有考虑的结构都表现出具有几何形状依赖宽度的高透射能带。

英文摘要:

Fullerene functionalized carbon nanotubes -- NanoBuds -- form a novel class of hybrid carbon materials, which possesses many advantageous properties as compared to the pristine components. Here, we report a theoretical study of the electronic transport properties of these compounds. We use both ab initio techniques and tight-binding calculations to illustrate these materials' transmission properties, and give physical arguments to interpret the numerical results. Specifically, above the Fermi energy we find a strong reduction of electron transmission due to localized states in certain regions of the structure while below the Fermi energy all considered structures exhibit a high-transmission energy band with a geometry dependent width.
