Magnetic Properties of Nitrogen-Doped Graphene Induced by Dopant Configurations

M. Chakraborty, Gregory C. Jensen, David C. Ingram, Eric Stinaff et autres

In this study, we experimentally demonstrate that the magnetic properties of nitrogen-doped graphene (NG) are influenced by the configuration of nitrogen dopants, namely graphitic, pyridinic, and pyrrolic, along with the overall nitrogen concentration. The NG materials were prepared via a two-step thermal …
