Abstract

This letter employs molecular mechanics simulations to analyze the geometric changes of foreign-atom-doped graphyne. Simulation results show that higher the density of dopant and the greater area covered by the dopant correlates to a greater folding angle of the graphyne sheet. Compared to graphene, graphyne folding could prove to be more effective for various nanodevices based on its unique band gap, especially when doped, and its tunable interactions with and absorption of foreign molecules. Therefore, our findings may offer unique perspectives into the development of novel graphyne-based nanodevices and stimulate the community's research interest in graphene-related origami.
