石墨烯表面顺磁性吸附物的电荷转移分析

Paramagnetic adsorbates on graphene: a charge transfer analysis

O. Leenaerts, B. Partoens, F. M. Peeters

摘要:

我们介绍了一种改进的Hirshfeld电荷分析方法,并通过计算顺磁分子NO2和石墨烯之间的电荷转移来证明其准确性。用从头算方法计算的顺磁性分子和石墨烯层之间的电荷转移可以关键地取决于计算中使用的超晶胞的大小。这对于涉及顺磁性分子如物理吸附在石墨烯或碳纳米管上的NO2的吸附研究具有重要的影响。

英文摘要:

We introduce a modified version of the Hirshfeld charge analysis method and demonstrate its accurateness by calculating the charge transfer between the paramagnetic molecule NO2 and graphene. The charge transfer between paramagnetic molecules and a graphene layer as calculated with ab initio methods can crucially depend on the size of the supercell used in the calculation. This has important consequences for adsorption studies involving paramagnetic molecules such as NO2 physisorbed on graphene or on carbon nanotubes.
