We investigated the resistance at the interface between carbon nanotubes (CNTs) and a probe-shaped titanium (Ti) wire upon annealing in vacuum. CNTs were attached to the end of the sharpened Ti wire by dielectrophoresis. The resistance was decreased by several orders of magnitude by annealing at 350 °C, which is lower than the temperature at which titanium carbide forms. The observed decrease in resistance by annealing at this moderate temperature is due to the removal of organic contaminants from the interface, which contributes to realizing direct contact between the CNTs and Ti while preserving a large contact area.
