Thin film resistance model
WebThe TFT is based on the assumption that a stagnant film will form on either side of any phase interface, that all resistance to oxygen transfer resides within the stagnant films … A four-point probe is used to avoid contact resistance, which can often have the same magnitude as the sheet resistance. Typically a constant current is applied to two probes, and the potential on the other two probes is measured with a high-impedance voltmeter. A geometry factor needs to be applied according to the shape of the four-point array. Two common arrays are square and in-line. For more details see Van der Pauw method.
