We have systematically investigated the fabrication of nanogap electrodes of Ni by the electrical break junction (EBJ) method under various environmental conditions. When EBJ was performed in the atmosphere, the anode side of the Ni electrodes was seriously damaged. The damaged region was analyzed by Auger electron spectroscopy and was identified to be Ni oxides formed during EBJ process by anodic oxidation via atmospherically-derived moisture adsorbed on the metal surfaces. When the EBJ process was performed in an evacuated environment, nanogap electrodes with atomic-order spacing were reproducibly fabricated even at room temperature.
