Contact potential, conduction current, and electrical contact resistance were measured in air and in vacuum as a function of the relative position of two carbon-nanotube coated electrodes. Contact resistance as low as 160 Ω was measured in ambient air as compared to higher than 4000 Ω when contact resistance was measured in vacuum. Electrical contacting behaviors and characteristics are reported. Effects of the ambient air on the measured electrical contact resistance are discussed.
