Abstract

We report a ferromagnetic graphene field-effect transistor with a band gap. The Mn-doped graphene has a coercive field (Hc) of 188 Oe and a remanent magnetization of 102 emu cm-3 at 10 K. The temperature-dependent conductivity indicates that the Mn-doped graphene has a band gap of 165 meV. A fabricated graphene FET revealed p-type semiconducting behavior, and the field effect mobility was determined to be approximately 2543 cm2 V-1 s-1 at room temperature.
