Zusammenfassung: | This investigation elucidates the influence of nitrogen doping (N-doping) on the magnetoresistance (MR) characteristics of graphdiyne (GDY) by methodically adjusting the levels of N-doping. Through exhaustive experimental analyses, encompassing SEM, XPS, and magneto-transport measurements, we demonstrate that N-doping markedly augments carrier concentration, thereby inducing distinct MR behaviors. Specifically, N
