Electro- and magneto-transport properties of amorphous carbon films doped with iron

► Iron chemically combines with carbon matrix. ► Amorphous-C: Fe films are a p-type semiconductor. ► Amorphous-C: Fe films have an isotropic MR at low temperatures. ► Amorphous-C: Fe films exhibit anomalous Hall effect. ► Amorphous-C: Fe/n-Si heterojunctions show a photovoltaic effect.
