▎ 摘　　要

NOVELTY - A nanotube probe (801) has a nanotube having multilayer coaxial tubular structure with openings at both ends. A graphene sheet layer formed by the vapor deposition method, has flake materials for coating the nanotube. The graphene sheet layer is coated with a metal coating layer. USE - Conduction characteristic measuring apparatus such as conduction characteristics evaluation apparatus and probe microscope. ADVANTAGE - The contact resistance between the probe and the needle substrate can be reduced by coating the nanotube with graphene sheet layer and wettability with respect to metal material can be improved reliably. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the conduction characteristics evaluation apparatus. Nanotube probe (801) Controller (804) Sample under measurement (805)
