To elucidate the conductive behaviour of transition metals (Mn, Fe, Co, Ni) doped C20 molecular device

Abstract

Fullerene molecular device configurations are center of allurement for varied number of electronic and transport characteristics by eccentricity of atoms epitomized in the same. In this paper, low bias conductive feature of smallest molecular device C20 has been observed using doping of transition metals. We examined the doping effect of manganese, iron, cobalt and nickel on C20 fullerene in a two probe device configuration. Using this configuration the C20 fullerene is oriented carefully between left and right gold electrodes. Transport properties were investigated and compared which highlighted the superiority of Mn doped device over pristine, Fe, Co and Ni doped C20 molecular devices.
