论文摘要
我们使用自旋偏振密度函数理论来研究磁性的磁性，该磁顺序是像kagomé一样的2D超材料，由原始的或替代掺杂的掺杂的明苯烯基自由基聚合到纳米孔，石墨烯样结构中。在此和较大的相关结构中，组成的多芳烃分子可以视为可能带有净磁矩的量子点。该多孔系统的结构和量子点之间的耦合可以通过施加中等应变来显着更改，从而可以控制磁性和基础电子结构。
We use ab initio spin-polarized density functional theory to study the magnetic order in a Kagomé-like 2D metamaterial consisting of pristine or substitutionally doped phenalenyl radicals polymerized into a nanoporous, graphene-like structure. In this and in a larger class of related structures, the constituent polyaromatic hydrocarbon molecules can be considered as quantum dots that may carry a net magnetic moment. The structure of this porous system and the coupling between the quantum dots may be changed significantly by applying moderate strain, thus allowing to control the magnetic order and the underlying electronic structure.
