Nanometer-sized rods were fabricated by an electron beam-induced deposition technique with iron pentacarbonyl. The electric properties of the as-deposited and heat-treated nanorods were measured in situ using a transmission electron microscope. The obtained current-voltage curve showed a nonlinear characteristic, and the resistivity was in the order of 10-2 Ω m in the case of the as-deposited nanorods. After a heat treatment at 600°C in vacuum, the nanorods transformed to α-Fe, and a resistivity of approximately 10-6Οm and a metallic characteristic were obtained. This suggests that position- and shape-controlled metallic nanowires can be formed by electron beam-induced deposition combined with heat treatment.
