论文摘要
石墨烯基里加米（图案切割）可以是改善某些石墨烯力学和电子特性的有效方法。在这项工作中，我们报告了单一和多层石墨烯金字塔基里加米（GKP）的机械和弹道行为的首次研究。我们进行了完全原子的反应性分子动力学模拟。 GPK呈现出独特的动能吸收，这是由于其拓扑造成的，从而产生了多个步骤的耗散机制，从而阻止了裂纹的传播。我们的结果表明，即使质量明显较小，GKP也可以在吸收能量方面胜过具有相似尺寸的石墨烯结构。
Graphene kirigami (patterned cuts) can be an effective way to improve some of the graphene mechanical and electronic properties. In this work, we report the first study of the mechanical and ballistic behavior of single and multilayered graphene pyramid kirigami (GKP). We have carriedout fully atomistic reactive molecular dynamics simulations. GPK presents a unique kinetic energy absorption due to its topology that creates multi-steps dissipation mechanisms, which block crack propagation. Our results show that even having significantly less mass, GKP can outperform graphene structures with similar dimensions in terms of absorbing kinetic energy.
