▎ 摘　　要

Adsorbed Li atoms on graphene can tune its electronic properties in favor of various applications. The tendency of Li atoms for clustering on a graphene surface remains challenging. Herein, adsorption of Li atoms on graphene through a self-assembling network is investigated and its stability is verified via molecular dynamic calculations. Among the various properties that Li-doped graphene can possess, we explore its optical properties by calculating its electron energy loss spectra (EELS). We demonstrate that the variation in the distribution of Li atoms on graphene results in different peaks in the EELS curves.
