Four probe resistivity measurement pdf
WebSheet resistance or resistivity Rs can be obtained using the following formula. RS = p/ln2 x V23/I14 Where: Rs= Sheet resistance measured using a Greek cross bridge or Van der Pauw sheet (ohm/square). V23= Voltage measured between contacts 2 and 3, or two adjacent pads. I14= Current forced between contacts 1 and 4, or two adjacent pads.
