Four- terminal measuring device that uses nanotube terminals

摘要

A four-terminal measuring device, which uses nanotube terminals and measures low resistance values and low impedance values of extremely small objects of measurement with good precision, comprising two current terminals which cause a constant current to flow from a constant-current power supply to an object of measurement and two voltage terminals which measure the voltage across both ends of the object of measurement; and in this four-terminal measuring device, a nanotube terminal is formed by fastening the base end portion of a nanotube to a holder so that the tip end portion of the nanotube protrudes from the holder, and such a nanotube terminal is connected to desired terminals among the four terminals.
