One technique for measuring the coefficient of this effect for a sample is to use an arrangement with four contacts named for van der Pauw. A type of spacecraft thruster named for this effect ionizes a gaseous propellant and then expels it using an electric field. In a semiconductor, the coefficient of this effect must take the hole mobility into account. In the inversion layer of a field effect transistor, the energy levels induced by this effect are quantized, as predicted by (*) von Klitzing. Its coefficient is inversely proportional to the carrier density, and this effect offers proof that carriers are negatively charged. For 10 points, name this effect in which a transverse voltage appears in a conductor when a magnetic field is applied.
