Abstract
Using density functional theory, the structural stabilities, electronic and magnetic properties of Fen (n=1–4) cluster adsorbed on armchair graphene nanoribbon (AGNR), Fen/AGNR, are systematically investigated. We found that the Fen/AGNR systems have high stabilities and large magnetic moments. For different-sized Fen, Fen/AGNR can be half-metal with 100% spin polarization (n=1–3) or semiconductor (n=4). These excellent electronic and magnetic properties show that Fen/AGNR systems can serve as possible candidates for designing new nanodevices with different functions.
