Measuring the resistivity of conductors is not rocket science!

April 14, 2016 Tektronix Experts

Characterizing a metal’s resistivity requires you to measure very low resistances (and therefore, low voltages) accurately. Many techniques used for metals are applicable to other applications, such as the resistance of superconductors, nanowires, graphene (a one-atom –thick form of carbon), and other nanomaterials.  All involve measuring small voltages in which the applied power must be kept low to prevent device self-heating.
