What it is

General reference — not yet source-verified

Four-point probe systems are metrology tools used to measure the sheet resistance of thin films by passing a current through two outer probes and measuring the voltage drop across two inner probes.

How it works

General reference — not yet source-verified

Four-point probe systems operate by pressing four equally spaced, spring-loaded probes onto the surface of a sample. A direct current is forced between the two outer probes, and the resulting voltage is measured across the two inner probes. The sheet resistance is calculated from the applied current and measured voltage, corrected by geometric factors that depend on the probe spacing and sample shape.
